INDIANAPOLIS — Kerry Collins came to Indianapolis to win a Super Bowl ring.

He may leave town without a win.

Two months after signing with the Colts, the 17-year veteran was placed on injured reserve with a concussion — a move that will definitely end his season, and possibly his NFL career.

It's been a strange year for Collins, who announced in July he was retiring, then was wooed out of retirement with a $4 million deal to be Peyton Manning's backup.

But when Manning had another neck surgery in early September, Collins was suddenly promoted to starter. And now, with Manning still not expected back at practice before December, it's Collins — not Manning — who is on injured reserve.

BUCS LOSE GRAHAM WITH TORN ACHILLES: Tampa Bay running back Earnest Graham will miss the remainder of the season because of a torn right Achilles' tendon.

Graham was injured during Sunday's 24-18 loss to Chicago in London. He's appeared in all seven games this season, starting the last two with LeGarrette Blount sidelined with a knee injury.

SEASON OVER FOR BILLS' MERRIMAN: The lights have been turned off on Buffalo Bills linebacker Shawne Merriman's season.

Merriman, who earned the nickname "Lights Out" when he was one of the NFL's most feared players, was placed on season-ending injured reserve on Tuesday because of a right Achilles' tendon injury. It's the same injury that forced the Bills to place him on IR last November after they signed him as a free agent following his release from the San Diego Chargers.

DOLPHINS SHUFFLE ROSTER AT QB: The Miami Dolphins' revolving door at quarterback spun anew Tuesday, when the team placed quarterback Sage Rosenfels on the reserve-non-football illness list and signed J.P. Losman, who last completed a pass in 2008.

A blood disorder sent Rosenfels to the hospital in August, and he said in a statement that he hasn't fully recovered.

"When I first joined the Dolphins, all tests showed that I was healthy and ready to go," Rosenfels said. "But after practicing for a few weeks, especially in the heat, some new indications made it obvious that I need to rest and allow my body to regain all requisite strength."

Rosenfels joined the team Oct. 6 after Chad Henne suffered a season-ending shoulder injury. The only other quarterback on the roster is Matt Moore, who this month became Miami's 16th starter at QB since Dan Marino retired.

Losman, a first-round draft choice in 2004, started 33 games in five seasons with the Bills, with 33 touchdown passes and 34 interceptions. He spent part of the 2010 season with the Seattle Seahawks but didn't play.

T.O. WORKS OUT, BUT NO NFL TEAMS ARE WATCHING: Terrell Owens' workout was watched by two television networks but no NFL teams.

The 37-year-old free-agent wide receiver participated in some drills and caught passes Tuesday outside Los Angeles in a showcase televised by ESPN and NFL Network. He tells ESPN "I definitely feel there are some teams out there that are interested."

Agent Drew Rosenhaus says on Twitter that he will be contacting teams Tuesday to tell them Owens "is immediately available to visit and work out for them. He could play this Sunday!"

Owens has been rehabilitating a left knee injury that required surgery. He played 14 games for Cincinnati last year, making 72 receptions with nine touchdowns.

VIKINGS' CORNERBACK FACES FELONY CHARGES: Minnesota Vikings cornerback Chris Cook was charged Tuesday with trying to strangle his girlfriend, leaving her with a bloody nose and lip in an alleged attack that jeopardizes his status with the team.

Cook was charged with felony domestic assault by strangulation, which carries a penalty of up to three years in prison and a $5,000 fine.

The 24-year-old Cook was arrested early Saturday and released from custody Tuesday on $40,000 bail.

He is barred from contact with the alleged victim and cannot leave Minnesota, which would prevent him from traveling with the Vikings to Sunday's game at Carolina.

Cook has a court appearance set for this afternoon.

According to the complaint, Cook became upset early Saturday when he found out his girlfriend of 10 months had spoken to an ex-boyfriend.

The woman told police Cook threw her on the bed at his home near the team's suburban headquarters in Eden Prairie, got on top of her, and grabbed her neck with an open hand, constricting her ability to breathe.

The complaint said the woman freed herself by grabbing Cook's hair, which he wears in shoulder-length dreadlocks. Cook then struck her in the ear, sending her crashing into a wall. As the woman ran to the living room, he grabbed her neck again and squeezed it.

Hennepin County Attorney Mike Freeman said at a news conference that Cook answered the door to the house and officers found the woman with a bloody nose and upper lip. She had marks on her neck and hemorrhaging in her eye, Freeman said, consistent with victims of strangulation. State guidelines call for a sentence of a year and a day, he said.
