Although New England Patriots coach Bill Belichick did not say whether tight end Rob Gronkowski would play in Sunday's opener, the team listed him as doubtful on Friday.
Gronkowski is recovering from arm and back surgery. Although his practice time has increased this week, there is little chance that he will play in Sunday's game against the Buffalo Bills. He might be back for the second or third game, however.
Undrafted rookie Zach Sudfeld is expected to be the Patriots' primary receiving threat among tight ends in Gronkowski's absence.
Patriots wide receiver Danny Amendola is expected to play despite a groin injury.
