Tampa Bay Buccaneers tight end Rob Gronkowski has multiple fractured ribs that threaten to sideline him for multiple weeks, sources told ESPN on Saturday.
Gronkowski did not travel with the Buccaneers to Foxborough for Sunday's game against the New England Patriots due to the effect that flying could have on his injury.
"We held out hope all week that Gronk would be ready," a team source told ESPN. "He's a different breed."
Gronkowski suffered the injury during Sunday's loss to the Los Angeles Rams but returned to finish the game.
