Pats' S Chung back on injury report

FOXBOROUGH, Mass. (AP) - New England Patriots starting safety Patrick Chung is back on the injury report.

Chung has a knee problem and was among 13 players listed Friday as questionable for the Patriots' playoff game Saturday night against the Denver Broncos. He was limited in practice after participating fully Thursday.

Chung missed seven games because of a foot injury before returning Jan. 1 in a 49-21 win over Buffalo.

The Patriots had a bye last weekend. Questionable status means there is a 50-50 chance a player won't play although most listed that way by the Patriots have played.

The other 12 were wide receivers Wes Welker and Matthew Slater, offensive linemen Logan Mankins, Sebastian Vollmer, Dan Connolly and Marcus Cannon, cornerback Kyle Arrington, safety James Ihedigbo, and linebackers Rob Ninkovich, Brandon Spikes, Dane Fletcher and Tracy White.
