Panthers' Sam Martin: Back in action Monday

Martin (hamstring) was activated off the active/non-football injury list Monday, Aaron Wilson of KPRC 2 Houston reports.

Martin returned to practice Monday after being sidelined with a hamstring injury for the first week of camp. The 35-year-old signed a one-year contract with Carolina in March after spending the last three seasons in Buffalo. He is expected to be the Panthers' starting punter once the regular season starts.
