The Tampa Bay Buccaneers added two players to their injury report Friday. Bucs running back Cadillac Williams and rookie wide receiver Sammie Stroughter sustained back injuries in practice Thursday and were limited in Friday's workout.

Both Williams and Stroughter are listed as questionable for Sunday's game vs. the New York Jets.

"Sammie tweaked his lower back yesterday," said Bucs head coach Raheem Morris. "He was limited today. We'll have to see.

"[With Cadillac] it's the same type of deal; a back tweak. He was limited today."

Should Williams, who leads the Bucs in rushing with nearly 600 yards, be unable to go Sunday, Bucs RBs Derrick Ward, Earnest Graham and rookie Kareem Huggins would attempt to fill that void against the Jets' No. 2-ranked defense in the NFL.

Stroughter was scheduled to replace Clifton Smith as Tampa Bay's return specialist. Smith went on injured reserve earlier in the week with a concussion.

Should Stroughter, who has made an impact as a slot receiver and fill-in return man, not be able to play vs. the Jets, Bucs WR Yamon Figurs and Huggins would be called on to return kicks and punts.

"We've got some experienced guys back there and guys who have done it before in games in the NFL should Sammy not be able to go," said Morris.

In other injury news, Bucs WR Michael Clayton (knee) missed his third straight day of practice and is listed as doubtful. Clayton likely will be replaced by WR Maurice Stovall for the second straight game.

Clayton initially injured his knee vs. the Atlanta Falcons nearly two weeks ago. He has just 14 catches on the season. Morris said the team isn't giving serious consideration to placing the former first-round pick on injured reserve just yet.

"I don't think we're there yet with the I.R. talk," said Morris. "We'll see where he is in practice next week and see what he can do by tomorrow and game day."

Like Clayton, Bucs cornerback Derrick Roberson (groin) and defensive lineman Michael Bennett (unknown) are also listed as doubtful.

Bucs linebacker Geno Hayes (hamstring) is questionable and tight end Kellen Winslow (knee) is probably for Sunday's contest vs. New York at Raymond James Stadium.

The Jets have their own injuries to worry about. Rookie quarterback Mark Sanchez (knee) has already been ruled out of Sunday's game. He will be replaced by QB Kellen Clemons. Guard Robert Turner (knee) and cornerback Dwight Lowery are also out.

New York G Alan Faneca (illness) and tackle Wayne Hunter (illness) are questionable.

Jets CB Marquice Cole (knee), defensive end Shaun Ellis (knee), CB Donald Strickland (concussion), safety Jim Leonhard (thumb) and linebacker Calvin Pace (shoulder) are probable for Sunay's game.
