Petty only suffered a bruised chest during Saturday night's loss to the Dolphins, NFL Network's Ian Rapoport reports.
Petty was feared to have suffered lung damage after being knocked out of Saturday's loss, but tests since then have fortunately checked out alright. As it stands, it's unknown if Petty's injury will impact his ability to practice this week or play Saturday against the Patriots, so his situation will need to be monitored as the week unfolds.
