Detroit Lions linebacker/defensive end Brandon Copeland tore a pectoral muscle in Sunday's preseason win over Indianapolis, will need surgery and is likely out for the season, according to a source.
Copeland was injured in the second half of the game, went to the locker room and did not return. Copeland had been a key special teams player for Detroit as well as a player who could play both linebacker and defensive end.
The injury was first reported by NFL Network.
He had been lining up with the No. 1 defense as a SAM linebacker at points during training camp and had been in a competition with Antwione Williams.
