Packers tight end Andrew Quarless suffered a season-ending knee injury last week that could potentially threaten the 2012 season as well. Bob McGinn of the Milwaukee Journal-Sentinel writes that the damage was so severe that it's very possible Quarless will miss all of 2012. A fifth-round pick in 2010, Quarless had 21 catches last year but his role as a receiver was diminished with Jermichael Finley back this year.
