PITTSBURGH -- Pittsburgh Steelers safety Ryan Clark says he didn't put up a fight when coach Mike Tomlin told Clark he couldn't play in Sunday's wild card game at Denver because of a blood condition that becomes aggravated when playing at altitude.

Clark called his talk with Tomlin on Monday "one- sided" and added he didn't protest because Tomlin isn't the kind of coach who changes his mind.

Clark nearly died in 2007 following a game in Denver when the sickle-cell trait he suffers from flared up. He lost his spleen and gall bladder in addition to losing 30 pounds.

Clark said he would have let himself play if the decision was up to him and was relieved when Tomlin stepped in.

Clark will make the trip and plans on helping replacement Ryan Munday as much as he can.

Pittsburgh Steelers quarterback Ben Roethlisberger says he aggravated his sprained left ankle in 13-9 win at Cleveland last weekend but expects to play in the wild card game at Denver on Sunday. Roethlisberger was limited in practice on Wednesday and walked into the trainer's room afterward with a noticeable limp.

Dolphins

Chicago Bears special teams coordinator Dave Toub is the latest candidate to interview for the Miami coaching job.

The Dolphins completed a two-day interview with Toub on Wednesday. They've also interviewed former Titans coach Jeff Fisher and Todd Bowles, who was Miami's interim coach for the final three games this season after Tony Sparano was fired. Toub has been with the Bears since 2004.

Packers

For Greg Jennings, being able to run again was nice. What happened y was a much bigger step in his recovery.

For the first time since injuring his knee last month, Jennings was able to run routes against the Green Bay defense in practice -- an indication that the Pro Bowl wide receiver is on track to return for the playoffs. Jennings tore his left medial collateral ligament in the Packers' Dec. 11 victory over Oakland, and sat out the final three games of the regular season.

Bills

The agent for receiver David Clowney told AP that his client has agreed to sign with Buffalo. Brian Mackler confirmed he had signed with the team. Clowney has been out of football since being waived by the Carolina Panthers before the start of this past season.
