FOXBOROUGH, Mass. -- Patriots tight end Kellen Winslow was not spotted at the start of Thursday's practice. His status is unclear. He was not listed on Wednesday’s injury report. (Update: Mike Reiss and Adam Schefter have reported that Winslow asked for and was granted his release by the Patriots)
Meanwhile, guard Logan Mankins (hip) remained out of practice for a second straight day. His absence at Thursday's full pads session puts his availability in doubt for Sunday's game in Buffalo.
Defensive lineman Brandon Deaderick, who was inactive on Sunday night with an ankle injury, returned to practice on Thursday.
