BEREA, Ohio -- Robert Griffin III has been dealing with more than just trying to win the Browns' starting quarterback job.

Griffin has been separated from his wife of three years, the former Rebecca Liddicoat, for the past several months, and he's in the process of filing for divorce, a league source told cleveland.com.

The couple got married on July 6, 2013, and had a daughter, Reese Ann Griffin, in May of 2015. Griffin has informed his teammates and coaches of the divorce, and they've been supportive, the source said.

Griffin was named the starting quarterback Aug. 8 and made his debut Friday night against the Packers. Browns players have complimented Griffin on his focus and dedication to the job.

Sources said that it's been a difficult time for Griffin, but that he's working through it with the help of friends and family.

The two were introduced by a mutual friend at Baylor in 2009 and Griffin proposed in October of 2010 in the school's fieldhouse, following the Bears' 47-42 victory over Kansas State.

They were married three years ago at the Denver Four Seasons in Colorado, because Liddicoat is a native of Boulder. Wedding guests included Baylor coach Art Briles, Redskins owner Daniel Snyder, and Redskins teammates Kirk Cousins, London Fletcher, Santana Moss and Pierre Garcon.

Despite what Griffin's been going through, he's become the strong, vocal leader that Hue Jackson wanted. He's managed to compartmentalize his personal and professional lives, and not let the situation negatively impact him on the job.

"He's a natural leader and that's what you need from an intangibles standpoint,'' Joe Thomas said recently. "Everyone knows how talented he is as an athlete and throwing the ball and the one thing that maybe guys didn't know about that have been really impressed with him so far is his work ethic, his intelligence, the way he prepares and he studies just like the great quarterbacks in the game right now.''

Linebacker Nate Orchard has grown close to Griffin over the past few months.

"To see him and where he's at now, and the swag he's got, it's fun, because that's what you want in a quarterback,'' he said. "You want him to be out there loose and enjoying himself, controlling that offense and you can see everyone gravitates towards him and they trust him and know he's going to do good things for us.''

Receiver Terrelle Pryor has also become a friend.

"He's chill. He's real relaxed. He Facetimes his daughter a lot,'' said Pryor. "He's a family guy. He's a teammate first, he's awesome.''

Receiver Josh Gordon played with Griffin at Baylor.

"Robert, we go back a long time and I think that'll be one of my best friends for the rest of my life,'' said Gordon. "I can't say enough about that guy. He looks out for me. That's part of my support staff. I know he's a big brother in that regard. As much as I need him, everybody else in this building needs him just as much."
