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, newly acquired veteran Jonnu Smith will likely operate as the primary backup behind starting tight end Tucker Kraft (knee).
