Browns coach Eric Mangini announced Tuesday morning that quarterback Brady Quinn has been placed on injured reserve with a left foot injury suffered on a bootleg run late in Sunday's 41-34 victory at Kansas City.
Mangini didn't rule out that Quinn might need surgery.
''It's hard to tell on film,'' Mangini said of what happened to Quinn. ''He and I were talking about it last night and even he wasn't sure exactly how it happened.''
Quinn was upbeat when he spoke to the media after the game and gave no hint that he'd been injured, although he was seen around the X-ray room. He was at practice Tuesday with a boot on his injured foot and using crutches.
Mangini said Derek Anderson will start the remaining two games at home against Oakland and Jacksonville. Brett Ratliff will be No. 2, Joshua Cribbs No. 3.
On third and 1 from the Cleveland 39 with 1:19 remaining, Quinn gained 24 yards on the bootleg around right end, helping set up the Browns' last touchdown with 44 seconds remaining.
Quinn finished the season 2-7 as a starter. He completed 53.1 percent of his passes for 1,339 yards with eight touchdowns, seven interceptions and a 67.2 rating.
The 22nd overall pick in the 2007 draft, Quinn is now 3-9 in limited duty as a starter during his three-year career.
''He had done a really nice job with a pretty radical transition to the no-huddle,'' Mangini said. ''A lot of things I was hoping for at the beginning of the season we really started to see in the later part of the season.''
The Browns went to the no-huddle after their Nov. 8 bye, when Quinn regained the job. Mangini benched Quinn at halftime of the Sept. 27 game at Baltimore, giving him just 10 quarters.
''He's done a lot of good things,'' Mangini said. ''I think the no-huddle helped him quite a bit. His ability to do that as well as he did helped us.''
