The NCAA's most prolific throwing arm has tossed his last competitive pass.

Former Hawaii quarterback Tim Chang, the nation's all-time leading passer, said he's hanging it up after playing for the Winnipeg Blue Bombers and Hamilton Tiger-Cats in the Canadian Football League the past two seasons.

Chang said he's returning to UH to finish his degree and will work in the athletic department's compliance office as a student assistant.

Chang finished his Hawaii career in 2004 with 17,072 yards and 117 touchdowns and had training camp stints with the Arizona Cardinals, Detroit Lions and Philadelphia Eagles. He also played with the Rhein Fire in NFL Europe.

The Saint Louis graduate was back on campus yesterday as a volunteer working at the Pacific Islands Athletic Alliance combine.
