Both sides must agree to the rollover. “We are looking forward to an exciting and successful season in 2007,” UCLA athletic director Dan Guerrero said. “With Karl solidifying his coaching staff, an experienced team returning and a terrific home schedule, we are poised to take the next step with our program.” LOS ANGELES – UCLA and Karl Dorrell mutually agreed to a one-year rollover of the football coach’s contract, which now runs through the 2011 season. Terms of the rollover year are the same as in the five-year contract Dorrell agreed to a year ago. He is guaranteed $850,000 annually, and can make another $505,000 in incentives. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
