Update: Gronkowski underwent surgery to repair his broken forearm Monday, NFL Network's Ian Rapoport reports
Recommendation: Rapoport suggests a 4-6 week timetable for his return, while Tom E. Curran of Comcast SportsNet New England suggests that Gronkowski is looking at a 4-8 week time-frame and ESPN.com chimes in with a vague, but slightly more optimistic expectation that he'll miss "probably a few weeks." Either way, a (very) late season return to the Patriots' lineup seems to be a best-case scenario here. While no one can directly replace Gronkowski in the team's offense, his absence will create added opportunities for Aaron Hernandez once he is healthy, while Visanthe Shiancoe, Daniel Fells and Michael Hoomanawanui (to a lesser degree) are candidates to see added looks as well. Which of the three is in line for the greatest spike in action remains unclear, though if we had to pick one right now, it would be Shiancoe, especially given that Fells was a healthy inactive on Sunday.
