Asiasi (undisclosed) has been activated off IR in advance of Thursday night's game against the Rams, Mike Reiss of ESPN.com reports.
Meanwhile, Ryan Izzo (hamstring/hand/neck) was placed on IR, leaving Asiasi, Dalton Keene and Jordan Thomas as the Patriots' available tight ends Week 14. Though Asiasi has some long-term potential, he has yet to record a catch through his first five games as a pro and therefore has much to prove before he can be considered for fantasy lineups.
