Jags upgrade linebacker Peterson for Steelers game

JACKSONVILLE, Fla. -- Jaguars linebacker Mike Peterson was upgraded to probable for Jacksonville's game Monday night against defending Super Bowl champion Pittsburgh, while receiver Matt Jones was added to the injury report with a sore groin.

Jones didn't practice Saturday and was listed as probable.

"Matt has a little bit of a tight groin, so we rested him today," coach Jack Del Rio said. "He's OK. It's just that it was tight, so we kept him out of practice."

Five others remained questionable: tight end Marcedes Lewis (ankle), guard Chris Naeole, safety Gerald Sensabaugh (ankle), defensive end Paul Spicer (groin) and defensive tackle Marcus Stroud (ankle).

Naeole hurt his knee in practice Thursday, but tests revealed no damage. Del Rio said Naeole's status will be a game-time decision.
