Aaron Colvin tears ACL at Senior Bowl practice...Oklahoma cornerback Aaron Colvin tore his ACL at Senior Bowl practice in Mobile, Ala., on Tuesday. Colvin left practice with his right knee heavily wrapped, and his agent, Ken Sarnoff, later confirmed the injury on Twitter. @AColvin14 has torn his acl. Send prayers for this terrific young cb and even better person who will make his mark in the NFL. - Jason Kersey, News Oklahoma Colvin has NFL talent, but he needs to harness it and eliminate the mistakes that have plagued him in high profile matchups. Physical corner with a tough-minded approach against the run and in coverage. Aggressive mentality can get him in trouble in coverage, drawing pass interference penalties with his hands-on approach. Susceptible to biting on play-fakes.
