He was signed by Baltimore in late 2003, then sent to the Rhein Fire of NFL Europe, but eventually cut by the Ravens.[2] After being cut for a fourth time, Harrison considered not playing anymore. Shortly after, he was signed a fourth time by the Steelers during training camp in 2004 after Clark Hagganssustained an injury in an offseason weightlifting accident. Showing much improvement, Harrison made the final roster and has remained with the Steelers since. Harrison later told the Beaver County Times that if not for Haggans’s injury, he planned to retire from football at age 26 to focus on becoming aveterinarian, something that Harrison still plans on doing after his football career ends. Harrison also considered following in his father’s footsteps and become a truck driver,[6] and to this day does have acommercial driver’s license.[8]
