NFL injury report: Rob Gronkowski undergoes surgery for broken forearm

After breaking his forearm during the fourth quarter on Sunday, New England Patriots tight end Rob Gronkowski underwent surgery on Monday.

Gronkowski had screws inserted into his forearm and although his timetable to return is still unknown, Gronkowski is reportedly eyeing a Week 14 return. Initial estimates expected Gronkowski to miss between four and six weeks, so a Week 14 return would put Gronkowski a full week ahead of the low end.

When asked during his Monday press conference, Patriots head coach Bill Belichick didn't have much of an update on Gronkowski's recovery.

"I don't really have anything," Belichick said, according to ESPN.com. "I know that our medical people are looking at all the players today when they come in, trying to assess their situation, like we always do on Monday."

While the Patriots will be without Gronkowski for at least a couple of weeks, they may get tight end Aaron Hernandez back this week. Hernandez has been out since Week 2 due to an ankle sprain, but is expected to return for New England's game against the New York Jets on Thursday.
