It appears Peyton Manning will miss more than this Sunday's opening game at Houston.
According to a report on ESPN.com, Manning underwent further neck surgery Thursday. It is not yet known if Manning would be able to return to play this season.
The news of this latest procedure, a reported cervical fusion, comes hours after Colts owner Jim Irsay wrote in a tweet Thursday morning that the quarterback is "out for awhile."
Manning, who has started every game for the Colts since 1998, underwent a second neck surgery in May. He was activated off the team's physically unable to perform (PUP) list on August 29, and his recovery slowed in the last week.
