Browns coach Mike Pettine didn't deny he demoted Johnny Manziel from starting quarterback to third on the depth chart earlier this week partly because the 22nd overall pick in last year's draft lied to him.



On Thursday, Fox Sports' Jay Glazer reported Manziel told the Browns the party video that surfaced online Monday showing him holding a large bottle while singing and dancing in an Austin, Texas, nightclub late last week was old. He also tried to get other partygoers involved to cover it up, according to the report.



When a reporter told Pettine during a news conference Friday it's come to light that Manziel lied to him and other members of the coaching staff, Pettine cut off the reporter.



"I already addressed it," Pettine said. "I said trust and accountability was where we had a shortfall. I have nothing more to add."



Earlier in the news conference, Pettine was asked why Manziel is still on the team after lying.



"I addressed this situation in detail on Wednesday," Pettine said. "When I say I'm sorry to disappoint, I'm not really. But I'm just not going there today. We've got a game to get ready for Monday night. I dealt with it Wednesday. I'm moving forward."



Josh McCown will start when the Browns (2-8) host the Baltimore Ravens (3-7) on Monday Night Football. Austin Davis will serve as the backup.



Meanwhile, Manziel is third on the depth chart and could be inactive.



"I haven't done the worksheet yet, but that always comes down to projected health, where we are at other positions," Pettine said. "So I haven't made that decision yet."



Browns offensive coordinator John DeFilippo said he supports Pettine's decision to bench Manziel "100 percent." He added Manziel's fall is "very disappointing."



Asked if Manziel lied to the coaches about the party video, DeFilippo said, "I'm going to leave those conversations between myself and coach."



But DeFilippo expressed optimism about Manziel bouncing back, leaving the door open for him to play again in the final six games.



"To say that Johnny Manziel won't play again this season, I'm not ready to say that," DeFilippo said.



DeFilippo also said he still believes Manziel can be a franchise quarterback.



"I know the person more than a lot of people," DeFilippo said. "We all make mistakes. We all hope as an organization he's learned from some of the mistakes he's made. We're all a work in progress. We're going to keep working with him."
