The extension was the second signed by the former Chicago Bears and Miami Dolphins coach since he was hired in December 2004. Pitt has a 19-7 record in the two seasons since Wannstedt signed his initial extension.
Wannstedt, 57, is promising that Pitt will be his last job, and he sought extra years on his contract so he could assure potential recruits he would be on the job throughout their college careers.
Wannstedt had a 16-19 record in his first three seasons, receiving his first extension hours before Pitt upset then-No. 2 West Virginia 13-9 to end the 2007 season -- a victory that made a significant impact on the Panthers' recruiting.
The Panthers went on to go 9-4 in 2008 and 10-3 last season, when they lost to Cincinnati 45-44 to end the regular season.
That last-minute defeat cost them a Big East title and an appearance in a BCS bowl game, but they rebounded to beat North Carolina 19-17 in the Meineke Car Care Bowl.
ALABAMA: Nose guard Josh Chapman doesn't feel like there will be much drop-off on Alabama's defensive line, even with three new starters.
Chapman has the biggest shoes to fill -- literally and figuratively. He's expected to replace two-time All-American Terrence Cody .
Chapman is several inches and 50 pounds smaller than Cody. But he's also one of the Crimson Tide's strongest players with a bench press he says is in the "high 500s."
The 6-foot-1, 310-pound Chapman frequently spelled Cody on third-down. He has played in 29 career games, which makes him something of a mentor to several promising defensive linemen.
OREGON: Quarterback Jeremiah Masoli is participating in spring practice even though he won't play a down for the Ducks this fall after his season-long suspension.
Masoli pleaded guilty March 12 to a misdemeanor burglary charge involving a theft at a campus fraternity house in late January. He was suspended by coach Chip Kelly within hours of his court appearance.
Masoli, touted as a possible Heisman candidate his senior season, is allowed to practice with the team during the suspension.
