ESPN's Ed Werder reported on SportsCenter Monday that the Patriots legitimately do not know when Rob Gronkowski will return from back surgery.
"The fact is the Patriots really don't know when he's gonna come back," Werder stated. The Pats will have a better feel once Gronk's back operation is performed Tuesday, but Werder reports Bill Belichick has prepared "many contingencies," and noted New England is currently carrying a league-high seven tight ends on its 90-man roster. Gronkowski will open camp on the PUP list, and we suspect he may stay there into the regular season.
