It was announced later in the week that Peterson suffered a torn meniscus, and he underwent surgery on Thursday. Other reports claimed that he also suffered a torn LCL, and the recovery time would be 3-4 months. He was placed on IR on Friday, meaning the earliest he could return is in week 11, which would be mid-November.
Minnesota head coach Mike Zimmer did admit that the possibility of A.D missing the rest of the season is still there. Zimmer stated "anything is possible."
Peterson twisted his knee at the end of a five-yard run, and left the game at the end of the third quarter. He does have a history of knee issues, including tearing both his ACL and MCL in 2011, which may diminish the chances of him returninig in 2016.
Another key running back that will for sure not see the field again in 2016 is Danny Woodhead of the San Diego Chargers. An MRI on Monday revealed a torn ACL in his right knee, which was suffered on Sunday.
The Chargers are now left with Melvin Gordon, Kenneth Farrow, and Andre Williams in the backfield.
The 31-year-old Woodhead was injured at the end of the first quarter in the game against the Jaguars. The incident occurred when he was tackled by linebacker Telvin Smith. This is now the second season-ending injury he has suffered in his career, as he also broke his ankle in week 3 of the 2014 season.
A separate key injury that is fortunately not season-ending is Doug Martin's of the Buccaneers. The running back is expected to miss three weeks with a strained hamstring. He left Sunday's game against Arizona in the second quarter after first tweaking the hamstring. The severity of the injury was announced on Tuesday following an MRI.
Martin was second in the NFL in rushing yards in 2015, while also averaging 4.9 yards per carry. He finished with just 23 yards on seven carries prior to Sunday's injury.
This comes just one season after the oft-injured star played in all 16 games, where he accounted for 72 percent of the Bucs' rushing yards. Tampa Bay will compete against the Rams, Broncos, and Panthers without Martin in uniform.
