Following a 24-13 loss to Indianapolis in the AFC divisional playoffs on Sunday, the 38-year-old, five-time MVP was asked if he planned to return for the 2015 season.
''I guess I just can't give that simple answer, I'm processing it,'' Manning said. ''So, I can't say that.''
As recently as Christmas Eve, Manning said he planned on being back next season if the Broncos wanted him.
Manning went 26 for 46 for 211 yards and a touchdown against the Colts. He struggled to find his rhythm, as has been the case since mid-November, when the Broncos started running the ball more.
He said he's been dealing with a thigh bruise since the Dec. 14 game against the Chargers, but said it felt good enough to play with coming into the playoffs.
