Mobile, AL (SportsNetwork.com) - Oklahoma defensive back Aaron Colvin reportedly tore his ACL on Tuesday during Senior Bowl practice.
The NFL Network first reported the injury, which was later confirmed by his agent.
Colvin, who recently graduated from Oklahoma, was expected to be taken somewhere in the first three rounds of the upcoming NFL Draft after a terrific season for the Sooners that saw him record 55 tackles -- five for a loss -- and an interception.
The injury could cost the 6-foot, 192-pounder his entire rookie season.
