Colts quarterback Peyton Manning underwent his third neck procedure inâ¦ (Brian Spurlock / US Presswire ) Indianapolis quarterback Peyton Manning, the NFL's only four-time most valuable player, underwent another neck surgery Thursday and could sit out the entire season and possibly more. It was the third neck procedure in 19 months for Manning, 35, who has missed only one play because of injury in 14 seasons. The development is probably crippling to the Colts, who scrambled to sign veteran Kerry Collins two weeks ago and will start him Sunday at Houston.
Injuries forced Brady and Manning to each miss a season. But they already have played long enough to ensure first-ballot election to the Pro Football Hall of Fame. Both are closer to 40 years old than 30, yet their fast releases will help them live for many more NFL days ahead.
