The Panthers were back on the practice field Wednesday as they gear up for Sunday’s trip to Atlanta. Three player’s missed yesterday’s practice. Safety Deke Cooper sat out with a groin injury. But Cooper told reporters he expects to play Sunday. Defensive end Stanley McClover was out with a thigh injury, and reserve linebacker Adam Seward sat out with an injured calf. The Panthers are 1-and-1 after last Sunday’s 34-21 loss to Houston. The 0-and-2 Falcons signed quarterback Byron Leftwich Tuesday, but Joey Harrington will remain the starter for Sunday’s game. The Panthers will practice later today.
