Bills vs. Dolphins injury updates: Stevie Johnson full participant

Three Buffalo Bills players are making health-related progress this week as the team continues preparations for Sunday's matchup with the Miami Dolphins.

Stevie Johnson was a full participant on Thursday a day after a lower back injury limited him. It's a great sign of progress for Buffalo's top receiver, and it's looking like he'll be on the field in South Beach to begin another streak of consecutive games started.

Kyle Williams (Achilles) was also a full participant after getting the day off on Wednesday, and C.J. Spiller (ankle) was limited after being held out of action yesterday. For Williams, Wednesday is his customary day off, and he'll be in the lineup on Sunday. Spiller is expected to play, though considering he has just 20 combined touches in his last two games, the size of his workload may not increase much.

EJ Manuel, out at least four weeks with a knee injury, was the only non-participant on Thursday. His replacement, Thad Lewis, participated fully for a second straight day and appears set to make his second straight start despite a minor foot injury. A trio of defenders remained limited for a second straight day: Mario Williams (hip), linebacker Manny Lawson (hamstring) and cornerback Ron Brooks (foot). Williams will suit up, but things are less certain with Lawson and, especially, Brooks, who hasn't played since Week 1.
