New England Patriots tight end Rob Gronkowski underwent surgery Monday morning to repair his broken forearm, according to ESPN's Adam Schefter.

Schefter's report did not offer a specific timetable for Gronkowski's return, but earlier, the Boston Herald had said the tight end would miss 4-6 weeks, which is the typical recovery time for a broken forearm to heal.
