PHOENIX -- New England Patriots starting center Bryan Stork, who injured his right knee in the divisional-round win over the Baltimore Ravens, is officially listed as questionable for Super Bowl XLIX.

A questionable designation gives a player a 50-50 chance to play.

Stork is the only player whose status is at that level. Defensive end Akeem Ayers (knee), quarterback Tom Brady (ankle), linebacker Dont'a Hightower (shoulder), defensive tackle Chris Jones (elbow) and defensive tackle Sealver Siliga (foot) are listed as probable. A probable designation reflects a virtual certainty that the player will be available.

One other note from the Patriots' participation report Friday: Cornerback Darrelle Revis was limited for non-injury reasons, with rest in mind.
