Despite his college success, Stubblefield was not selected in 2005 NFL Draft. He signed as an undrafted free agent with the Carolina Panthers, but failed to make the team as a wide receiver or return man. Stubblefield then signed with the Hamilton Tiger-cats of the Canadian Football League. During the 2006 season, he was invited to training camp with the St. Louis Rams, but once again didn't make the team. He was re-signed by the Tiger-cats, but he never recorded any statistics while he was on the team.
