Jansen (hand) wasn't listed on Carolina's injury report Wednesday, Brendan Marks of The Charlotte Observer reports.
It's tough to be a long snapper with a hand injury, so Jansen's quick recovery is great news for Carolina's special teams.
Jansen is tending to a hand injury, Joe Person of The Athletic reports.
It's unclear how serious the injury is or how Jansen sustained it. In his absence, Carolina signed Andrew DePaola to play in Saturday's preseason matchup against the Steelers.
