Peyton Manning suffered two ankle sprains, including a high ankle sprain, against Jacksonville on Oct. 13, league sources confirmed after an ESPN review of every offensive snap the Broncos star quarterback took against the Jaguars and in last week's game against the Colts.
Manning suffered the first ankle sprain on the Broncos' first offensive play against the Jaguars. The four-time MVP sustained the second sprain when he was hit low by Jacksonville's Jason Babin.
The high ankle sprain was aggravated during last Sunday's loss to the Colts, when Manning was sacked for the second time by former teammate Robert Mathis. Manning could be seen visibly on the game tape grabbing his lower leg just above his right ankle.
Scans of the injuries were sent to foot and ankle specialist Dr. Robert Anderson, who confirmed the high ankle sprain but determined that the injury was not severe, according to a league source who was informed of the video evidence.
Manning, who missed practice Wednesday but returned the following day, was expected to rely on a painkiller in Sunday's game against the Washington Redskins.
He came through for the Broncos in the team's 45-21 come-from-behind victory, going 30 of 44 for 354 yards with four touchdowns, but also contributed three interceptions and a lost fumble.
The Broncos have a bye next week.
The 37-year-old Manning is in his second season since returning from spinal fusion surgery.
