Ian "Rocky" Butler (born August 7, 1979) is a former quarterback who last played professionally in the Canadian Football League.
In 2001, he finished second in voting for the Walter Payton Award, given to the top player in the NCAA Division I Football Championship Subdivision.
But after a bizarre rash of injuries to all three of Saskatchewan's roster quarterbacks, Butler earned his first CFL start in the 2002 Labour Day Classic against the powerful Winnipeg Blue Bombers.
Although he only completed 9 of 16 passes for 165 yards that day, he rushed for three touchdowns and helped the Riders score a convincing upset victory.
In 2006, Kerry Joseph, the Riders starting quarterback, was injured and unable to start a game against the Hamilton Tiger-Cats, and backup Marcus Crandell was injured earlier in the game, and Butler pulled off two more wins against the struggling Tiger-Cats, 43-13 and 51-8, and threw for five touchdowns and ran for two more.
