-- RB Chris Perry is out indefinitely with an ankle injury, spurring rumors that he could be placed on the Injured Reserve list. Some of his teammates are saying that he could be healthy in time for the playoffs. Perry is the second-string running back who is their best pass-receiving back. FB Jeremi Johnson is expected to get some more reps in his place.
-- QB Ben Roethlisberger's ability to throw the deep pass is apparently still being impacted by an injured thumb, but he is expected to play this weekend.
-- Starting left offensive tackle Marvel Smith is expected to miss this weekend's game with an ankle injury.
-- After a lackluster performance against the Colts, Fred Taylor (19 yards on 10 carries) will continue to split time at halfback with fullback Greg Jones. "I see us utilizing both players,'' head coach Jack Del Rio said.
-- QB Byron Leftwich is expected to get a new X-ray of his broken ankle to check the healing process, but there appears to be little optimism that he'll be back this season.
-- Both starting safeties for the Patriots, Artrell Hawkins and Eugene Wilson are uncertain for this week's game due to injuries.
-- Starting RCB and returns specialist Darrent Williams will miss the rest of the regular season -- and possibly the playoffs up to the AFC Championship, should the Broncos get that far -- due to a groin tear. His absence impacts a number of areas for Denver. Dominique Foxworth will move into his cornerback spot on the defense. Safety Curome Cox will move into Foxworth's nickel back role. CB Roc Alexander will have to step in and handle kickoff returns while WR Charlie Adams will handle punt returns.
-- Larry Johnson is the hottest running back in the NFL since November 1st. Johnson has 852 rushing yards, six consecutive 100-yard rushing games and 10 rushing touchdowns since that date.
-- RB LaDainian Tomlinson's sore chest is feeling better than last week. Over the past four weeks, he had a huge game against Washington three weeks ago with 184 rushing yards, but in his other three games over the past month he had just 67, 86 and 75 yards.
-- Starting free safety Bhawoh Jue might not be able to practice this week due to a knee injury, but does expect to play.
-- TE Antonio Gates had 123 yards on 13 receptions during Week 14. He has a career-high 997 yards receiving this year with three games remaining.
