Musgrave (neck) was moved to the reserve/PUP list Sunday, Wes Hodkiewicz of the Packers' official website reports.
Musgrave missed the entirety of the preseason while on the active/PUP list with a neck injury that he suffered during OTAs in June. The oft-injured tight end will now be forced to miss at least four contests to open the regular season. In his absence, new-acquired veteran Jonnu Smith will likely operate as the primary backup behind starting tight end Tucker Kraft (knee).
