Hoping his knee would heal in time so he could be on the field down the stretch, the Packers kept Martin on the roster but made him inactive for the games against Houston and St. Louis.
"I wanted to wait and give him a couple weeks and see if he was going to come around," coach Mike Sherman said. "We worked him out this morning, visited with the doctor and the prognosis was not very good."
Martin's season ends with a career-low five catches for 88 yards. A college wide receiver at Tennessee, Martin has tremendous athleticism for his size but that never came through in the games. He will be an unrestricted free agent at season's end.
To fill the fourth-year pro's spot on the 53-man roster, the Packers activated 320-pound defensive tackle Colin Cole. Cole will provide depth behind starter Grady Jackson and his backup, James Lee. Both injured their knees earlier in the season, so Cole, a first-year player out of Iowa, will provide "added depth that we need," Sherman said.
"Cole is a stout run-defender, in practice we really struggle blocking him," Sherman said.
