Packers tight end Andrew Quarless (knee) was placed on the IR/designated-to-return list Wednesday, the Packers' official site reports.
Quarless' sprained MCL was expected to required 4-6 weeks of recovery anyway, so he should be approaching full health when he's eligible to return in eight weeks.
In the interim, Kennard Backman will move into the backup tight-end role, but expect another body to enter the TE ranks in the near future.
