THE SPORTS XCHANGE PREDICTION: Dolphins 20-17
KEYS TO THE GAME: With rookie Jonathan Baldwin starting to produce opposite Dwayne Bowe, Chiefs QB Matt Cassel has a pair of tall, physical wideouts to go get the ball. Miami's secondary has been a sore spot, so the Dolphins must bottle up RB Jackie Battle with the front seven, freeing the safeties to support the corners. Miami finally saw RB Reggie Bush's big-play flair last week, but still hopes Daniel Thomas (hamstring) can return to attack between the tackles. QB Matt Moore (rib) is playing banged up and only WR Brandon Marshall truly threatens downfield.
FAST FACTS: Bush is averaging 6.2 yards per carry the past three games, but on only 35 attempts. ... OLB Tamba Hali has six of the Chiefs' nine sacks.
-- C Mike Pouncey (neck) returned to practice on Thursday and worked in full. He had sat out on Wednesday.
-- LB Jason Taylor (hip) returned to practice on Thursday and worked in full. He had sat out on Wednesday.
-- RT Marc Colombo (knee) returned to practice on Thursday and worked in full. He also sat out on Wednesday.
-- CB Vontae Davis (hamstring) continues to be limited, as he has been for the past several weeks. He didn't practice on Wednesday but did work some on Thursday.
-- RB Daniel Thomas (hamstring) was limited on Thursday and his status is unknown for the game on Sunday. Thomas has sat out three games this season with a hamstring injury.
-- SS Jon McGraw suffered a shoulder injury in the Chiefs' victory Monday night over San Diego and has not gotten on the practice field this week. McGraw has been in the starting lineup as a replacement for the injured Eric Berry (knee) who is out for the season.
-- CB Javier Arenas sat out the Chiefs' practice session on Thursday but is expected to be back on Friday and ready to play this Sunday against Miami. Arenas said it was simply a precautionary measure, but he would not describe the injury.
-- RB Thomas Jones has had great success running against the Miami Dolphins over the last five years. Jones ran for 110, 101 and 102 yards facing the Dolphins' defense in 2007-08-09. Over his 12-season career, Jones has rushed for 382 yards on 94 carries against Miami.
-- QB Matt Cassel has one career start against Miami. It came while he was with New England in 2008; it was his second start after replacing an injured Tom Brady. The Patriots lost by 25 points, with Cassel completing 19 of 31 for 131 yards, with one touchdown pass and one interception. He lost a fumble and was sacked four times.
