WHO: Buffalo Bills (5-4) at Miami Dolphins (2-7)
KICKOFF: Sunday, 1 p.m. ET
SITE: Sun Life Stadium: SURFACE: Natural grass
TV: CBS, Marv Albert, Rich Gannon
THE SPORT XCHANGE PREDICTION: Dolphins, 24-21
KEYS TO THE GAME: Injuries remain a bugaboo for Buffalo, which is shuffling its offensive line yet again. WR Stevie Johnson (shoulder) hasn't made a major impact in the last two games, just as the Dolphins have turned up the heat to outscore Kansas City and Washington 51-12. Pinning RB Reggie Bush inside is mandatory for the Bills, who've allowed 11 rushing touchdowns and 4.6 yards per carry. Buffalo has just 15 sacks, and 10 came against the Redskins. Dolphins QB Matt Moore has completed more than 70 percent of his passes the past two games, looking downfield to WR Brandon Marshall frequently, a matchup that certainly doesn't favor the Bills.
FAST FACTS: Marshall had 19 catches in two games vs. Buffalo last season. ... The Bills averaged 30.1 points in the first seven games, 9.0 in the past two.
-- RB Fred Jackson is eighth among all players for the Pro Bowl in voting so far by fans. He's the top vote-getter among AFC running backs. Jackson has 1,309 yards from scrimmage heading into Sunday's game at Miami.
-- WR Stevie Johnson, who didn't practice Wednesday, returned on a limited basis. He continues to get treatment on a tender shoulder and his status for the Dolphins game is questionable.
-- WR David Nelson missed practiced Thursday due to sickness but the team is hoping he'll be fine for Sunday's game at Miami. Nelson is also dealing with an ankle issue.
-- C Eric Wood had surgery to repair his right ACL on Thursday. He tweeted that the surgery went well and he was ready for the long recovery. He has been placed on injured reserve.
-- LB Chris Kelsay (calf) was limited for a second day but was able to take most the snaps in practice and should be fine for Sunday's game vs. Miami.
-- DE Spencer Johnson missed his second day of practice with a calf injury. He'll likely be a game-time decision.
-- SS George Wilson missed his second day of practice with a neck ailment. The club is hoping he'll be able to go Sunday in Miami. Wilson leads the club in tackles with 77 and interceptions with four.
-- PK Rian Lindell, who has a broken shoulder, remains out. Free agent Dave Rayner will play in his place at Miami.
-- TE Anthony Fasano, who suffered a right ankle injury against Washington, practiced on a limited basis on Thursday, a day after sitting out Wednesday's sessions. Fasano, a four-year starter for the Dolphins, will likely be declared questionable for Sunday's game against Buffalo.
-- WR Davone Bess will likely receive significantly more playing time if TE Anthony Fasano doesn't play, or is limited against the Bills because of his ankle injury. Fasano's absence would likely mean the Dolphins lean more on its three-receiver sets, which uses Bess primarily in the slot. This season Bess has caught 32 passes for 360 yards, but he hasn't scored a touchdown.
-- CB Nolan Carroll, who aggravated his hamstring injury against the Chiefs two weeks ago and sat out last Sunday's game against the Redskins, practiced for the second straight day.
-- C Mike Pouncey, a rookie the Dolphins selected 15th overall in the 2011 draft, has gotten to the point the team is comfortable with him making all of the offensive line calls.
-- FB Charles Clay, a rookie H-back who also doubles as a tight end, has been working with the starters in TE Anthony Fasano's absence. Clay has caught eight passes for 133 yards this season.
-- DE Kendall Langford, a three-year starter most expected would have a big year considering he's a free agent at the end of the season, is at risk of losing playing time, if not his starting spot, to Jared Odrick. So far this season, Langford has contributed 12 tackles, one sack and forced one fumble.
-- TE Will Yeatman, a rookie the Dolphins claimed off the waiver wire, hasn't played in a single game this season. Coach Tony Sparano acknowledged the Dolphins as "slow cooking" the former Maryland lacrosse player, who was in camp with the Patriots.
