Coly Lyerla suffered a torn MCL and PCL in his right knee during practice and will likely miss the entire 2014 season.
Lyerla drew comparisons to Jimmy Graham and Rob Gronkowski at tight end coming out of Oregon, but went undrafted and signed as a free agent by the Green Bay Packers.
Lyerla quit the team in October and later pleaded guilty to the unlawful possession of cocaine.
