Bills injury updates: positive steps for several key starters

Five Buffalo Bills starters returned to the practice field on Thursday after sitting out Wednesday, but all of them did so in a limited capacity. Wide receiver Stevie Johnson (hamstring), right guard Kraig Urbik (knee), defensive lineman Kyle Williams (Achilles), pass rusher Mario Williams (ankle) and cornerback Leodis McKelvin (hamstring) all took a positive step in their bid to play on Sunday against the Baltimore Ravens.

Also limited on Thursday: defensive lineman Marcell Dareus (ankle) and safety Jairus Byrd (foot). Byrd, for the record, appeared to take a positive step simply based on his practice habits; WGR 550's Joe Buscaglia has the details there.

Four players that have been injured for several weeks did not participate: wide receiver Marquise Goodwin (hand), cornerbacks Stephon Gilmore (wrist) and Ron Brooks (foot), and kicker Dustin Hopkins (groin). That quartet is expected to miss this weekend's game.

Finally, two players that were full participants on Wednesday remained so on Thursday: running back C.J. Spiller (quad) and offensive lineman Doug Legursky (knee) both appear to be on track for playing time availability on Sunday.
