"As Derek Anderson limped out of the locker room Sunday, disdaining crutches despite the pain in his knee, a friend wished him luck and he answered, ''I'll see you, probably in another lifetime.''

Anderson thought he'd played his last game for the Browns, perhaps for his career. He learned Monday that's the case for the rest of this season.

An MRI revealed Anderson suffered a torn medial collateral ligament in his left knee in Sunday's 10-6 loss to Indianapolis. But surgery will not be required.

The Browns said he will wear a brace and is expected to recover in four to six weeks, which means he's headed to the injured reserve list.

Ken Dorsey, who hasn't completed a pass in the NFL since 2005, will take over as Cleveland (4-8) visits Tennessee (11-1) Sunday. Dorsey went 2-8 for San Francisco in 2004-05.

Dorsey will be without one of his go-to guys from the University of Miami, where Dorsey was 38-2 and led the Hurricanes to the 2001 national championship. An MRI showed tight end Kellen Winslow suffered a high left ankle sprain against the Colts and will miss the Titans game. He'll wear a boot for up to a week.

Now coach Romeo Crennel turns to his third starting quarterback in three weeks. Signed to a three-year, $24 million contract on Feb. 29, Anderson now carries a 13-14 record for Cleveland

over three seasons. This year, he completed 50.2 percent of his passes for 1,165 yards and nine touchdowns with eight interceptions and a 66.5 rating. He was sacked 14 times, his same total for 16 games a year ago.

A Pro Bowler who led the Browns to a 10-5 record in 2007 and threw 29 touchdowns, Anderson was benched after going 3-5 in 2008. But Brady Quinn fractured his right index finger Nov. 17 at Buffalo and further injured it by playing the following week against Houston. Quinn is on injured reserve and still debating whether to have surgery.

''Once Derek came back in, we were all confident because we know Derek can play, and it's frustrating now that we have to change again,'' left guard Eric Steinbach said Monday night at a Browns charity event. ''Derek is a tough guy and he would battle if he could.''

Browns radio analyst Doug Dieken said Monday on WKYC's The Point After that Anderson dislocated his finger on a handoff to running back Jamal Lewis against the Colts, but merely called timeout and had it popped back in place.

Crennel said the Browns would also look for a veteran backup quarterback who ''has some background in the system.'' Serving as No. 2 against the Titans will be receiver and special teams ace Joshua Cribbs, the former Kent State quarterback. Richard Bartel, a Tarleton State product signed to the practice squad Wednesday, might be called up if a veteran is not brought in. He spent 2007 on the Dallas Cowboys' practice squad.

Anderson was hurt with 1:07 remaining against the Colts when right tackle Kevin Shaffer was bull-rushed by defensive end Robert Mathis for
