Patriots' Harvey Langi: Activation window opens

Langi (knee) returned to practice Thursday, opening the three-week window for him to come off IR, Mike Reiss of ESPN reports.

Langi has been sidelined since spraining his MCL in Week 7. He played primarily on special teams prior to being injured. Langi could suit up as soon as Monday in Buffalo, but he'll first need to be removed from IR in order to do so.
