The New England Patriots won by a big margin Sunday over the Indianapolis Colts, but lost one of their biggest weapons in the process, as tight end Rob Gronkowski suffered a broken forearm late in the game.

Gronkowski, according to the Boston Herald, will miss four to six weeks with the injury, which essentially amounts to most or all of the remainder of the regular season.

Gronkowski suffered the injury on an extra point following a late Patriots touchdown in a 59-24 rout of the Colts.

Gronkowski has been Tom Brady's biggest weapon this season, with 53 catches for 748 yards and 10 touchdowns.
