BOSTON (CBS) – New England Patriots guard Dan Connolly and six other players are listed as “questionable” for Sunday’s Gillette Stadium opener against the Arizona Cardinals.

Along with Connolly, who suffered a head injury in last Sunday’s 34-13 win over the Titans, corner Alfonzo Dennard (hamstring), tight end Daniel Fells (shin), offensive lineman Nick McDonald (shoulder), corner Sterling Moore (knee), running back Shane Vereen (foot), and offensive tackle Sebastian Vollmer (back) are all listed as “questionable,” giving them a 50-50 chance of playing on Sunday.

After sitting out Wednesday’s practice, Connolly returned with limited participation on both Thursday and Friday.

On Friday, the Patriots had perfect attendance at practice, with the six “questionable” players all limited.

Safety Patrick Chung was the only other player to appear on the practice report, and is “probable” with a shoulder injury.

Cardinals quarterback John Skelton is listed as “doubtful” after suffering an ankle injury last week, meaning the Patriots are likely to see Kevin Kolb under center for Arizona on Sunday.
