Jason Whitlock’s role as the head of ESPN’s The Undefeated has ended before it even really began.

The journalist has exited as editor-in-chief of the website that focuses on the intersection of race and sports, ESPN announced in a statement on Friday.

Whitlock will be replaced on an interim basis by Leon Carter, formerly of the New York Daily News and ESPNNewYork.com, who will assume all day-to-day management of the site’s editorial processes and personnel.

Built largely around Whitlock and his brand, The Undefeated was first announced in Aug. 2013 and is currently “coming summer 2015,” according to its landing page. There are five features on the site, including two written by Whitlock, who has long been a leading voice on race issues.

“Jason Whitlock is just going to be used more to his strengths and let the editors and managers do their thing,” a person with knowledge of the situation told TheWrap. “It was a mutual decision — Jason is smart enough to know his strengths.”

The insider went on to say that the delay of the site, which has been dubbed “the black Grantland,” could not be sugarcoated: “It has taken longer than it should to launch a site, but that means they [ESPN] want to get it 100-percent right and start off with best possible way of succeeding.”

The management shuffle at The Undefeated comes a little over a month after ESPN and Grantland editor-in-chief Bill Simmons ended their tumultuous relationship. Grantland, which Simmons started in 2011, has continued with award-winning journalist Chris Connelly being named as interim editor-in-chief.

Both Grantland and The Undefeated are part of ESPN’s Exit 31, the umbrella content unit also responsible for ESPN Films and Nate Silver’s FiveThirtyEight, which is overseen by Marie Donoghue, ESPN Executive Vice President for Global Strategy and Original Content.

As we continue to move forward in the process of creating The Undefeated – a new ESPN site focusing on race and sports – we have collectively decided to make some structural adjustments that will maximize the skill sets and strengths of our team, leading to the best possible output for the site and for all of ESPN. To that end, Jason Whitlock will now be entirely focused on what he does best: creating distinctive and compelling content, which will live across various ESPN platforms. Jason’s thought-provoking perspective has always been a hallmark of his work and this will allow him to completely devote his time and energy to that. As a result, he will make significant contributions to multiple ESPN entities and programs. Since returning to ESPN, Jason has been instrumental in assembling the foundation of a strong editorial team, formulating the vision for the project and collaborating with our digital product team to develop the blueprint for the site.

Leon Carter – an experienced leader in journalism who officially joined the site in January after leading staffs at the New York Daily News and ESPNNewYork.com – will assume all day-to-day management of the site’s editorial processes and personnel on an interim basis.

18 Dramatic Championship Sports Movie Moments: From 'Rocky' to 'Remember the Titans' (Photos)

"The Pride of the Yankees" (1942)

This beautifully dramatized moment of sports history, as wonderfully monologued by Gary Cooper, helped to immortalize the already infamous "Luckiest man" speech by Lou Gehrig.
“Rocky” (1976)

In the ultimate underdog story, newcomer Rocky Balboa (Sylvester Stallone) gets a shot at the world heavyweight title against champ Apollo Creed. Rocky proves he has the goods, going the entire 15 rounds against Creed, but loses in a split decision. Rocky would get a rematch though and win the title in “Rocky II”.
"Breaking Away" (1979)

One of the most inspiring underdog stories ever made, the Little 500 bicycle race in Bloomington, Indiana, is a local classic as made famous by this film. In the film's closing race scene, the locals -- dressed in plain white T-shirts with their nickname the "Cutters" -- upset the richer college students with more expensive bikes and uniforms, riding across the finish line in pure glory.
“Chariots of Fire” (1981)

Two Englishmen push each other to be the best sprinter at the 1924 Olympics. While they won gold on the big screen’s racetrack, “Chariots of Fire” would go on to win Oscar gold for best picture.
“The Natural” (1984)

Robert Redford plays middle-age rookie Roy Hobbs in “The Natural.” Hobbs leads his team to a championship on his final at-bat when he launches the most famous home run in movie history. Thus proving the unspoken rule in baseball: If you break the lights you win the game.
“Hoosiers” (1986)

Another Indiana classic in what is widely considered one of the greatest sports movies of all time, “Hoosiers” follows a small town high school basketball team as they make it all the way to the state finals. They play a bigger and more athletic team in the finals, but with a last second shot pull off the surprise victory.
“Major League” (1989)

Charlie Sheen and Tom Berenger lead an outfit of misfit Cleveland Indians from last place to a shot at the league pennant against the powerhouse Yankees. Even though the film is a comedy, the final game plays out in dramatic fashion.
“A League of Their Own” (1992)

“A League of Their Own” proved that girls can play baseball, and ends in a play at the plate that determines the championship. Geena Davis’ Rockford Peaches may lose that final game, but as Tom Hanks taught us, “there is no crying in baseball!”
“Hoop Dreams” (1994)

Steve James’ revolutionary documentary follows inner-city Chicago kids William Gates and Arthur Agee throughout their high-school basketball careers. The film culminates in both striving to reach the finals of their city wide championship tournament.
“Remember the Titans” (2001)

Based on the true story of Virginia’s first integrated high school football team (led by coach Denzel Washington), the Titans not only change the views of an entire town, but they go undefeated on their way to a thrilling state championship against an all-white team.
“Friday Night Lights” (2004)

The film that spawned the critically acclaimed TV series (which in turn may spawn a film of its own) is memorable in that its featured team doesn’t win the championship. The Permian Panthers mount a great comeback, but come up one yard short of the state title.
“Miracle” (2004)

In perhaps one of the greatest upsets in sports history, a team of U.S. college hockey players defeated the Soviet Union, the three-time defending gold medal winner and best team in the world, during the Cold War.
"DodgeBall" (2004)

Okay, okay. This is really a parody of sports movies. But for all its send-ups of underdog sports movie formulas, it also embraces them full-heartedly during the gripping championship showdown between the Average Joes and Globo Gym.
“The Fighter” (2010)

David O. Russell‘s Oscar-winning picture depicted boxer Mickey Ward’s (Mark Wahlberg) climb up the ranks from middling contender to a shot at the title. The final fight shows the grit and heart that it took for Ward to win the belt.
"Senna" (2010)

The best sports documentaries are as riveting as their scripted counterparts, putting viewers right in the action as if they are watching it unfold live. "Senna" is one of the finest examples, using primarily archival footage with no narration and few interviews to show the bitter Formula 1 rivalry between Ayrton Senna and Alain Prost that led to the 1989 and 1990 championships being decided in controversial fashion at Japan's famed Suzuka Circuit.
"Survive and Advance" (2013)

ESPN's "30 for 30" series included a look at arguably the most famous championship run in college basketball history. In 1983, Jimmy Valvano led the North Carolina State Wolfpack on a streak of nine consecutive overtime or one-point wins, culminating in a last-second basket to win the championship over top-ranked Houston. In this documentary, even though the outcome is known, every game's heart-stopping drama is recreated perfectly.
"Creed" (2015)

The power and hypnotic beauty of this famous running scene from "Creed" as directed by Ryan Coogler is immense. Michael B. Jordan captures the inspiring training run from the original "Rocky" with a modern spirit. You can feel the emotion of the moment so strongly and can't help but root for him.
"Celtics/Lakers: Best of Enemies" (2017)

Another ESPN documentary that puts you right in the moment. Narrated by Lakers fan Ice Cube and Celtics fan Donnie Wahlberg, this five-hour doc covers the most famous championship rivalry in sports, which peaked with Magic Johnson and Larry Bird in the 80s. The tension hits its peak with Game 4 of the 1987 NBA Finals, in which Bird infamously missed a game-tying three-point shot.
