The 49ers will host Aaron Colvin, an Oklahoma cornerback who tore his ACL in January and who spent the first part of the year in Florida rehabilitating alongside a slightly more famous ACL patient, NaVorro Bowman. Colvin tore his ACL Jan. 21 during a practice at the Senior Bowl. Bowman suffered his injury Jan. 19. The surgeries were performed by famed orthopedic surgeon James Andrews, and both players rehabilitated at Andrews' clinic in Pensacola, Fla.
The 49ers, of course, drafted two players with ACL injuries last year, defensive end Tank Carradine and running back Marcus Lattimore. Neither played in 2013. Because Lattimore never appeared on the 53-man roster, his contract tolled. That is, he still has four years on his initial contract.
In that way, adding injured players to a loaded roster has become a draft strategy for the 49ers. They are able to obtain a player in a lower round because he is injured and perhaps allow him to "redshirt" his initial year with the team.
Colvin's injury, however, is not nearly as severe as Lattimore's, which involved several ligament tears and a dislocated kneecap. Colvin's agent said Sunday that the rehabilitation has gone very well and that the 6-0, 186-pound, two-time All-Big 12 cornerback will start running later this month. Colvin's injured occurred in Mobile, Ala. The next morning, he was in Dr. Andrews' office - a short drive away - in Pensacola. The surgery occurred the following week.
Team ACL: Other draft prospects with ACL injuries
DL Dominique Easley, Fla.: Easley was a first-round talent before tearing his ACL in September. He also suffered an ACL injury as a sophomore. Easley will have a private workout on Thursday. The 49ers are expected to attend.
G Brandon Thomas, Clemson. He was considered one of the better interior linemen in the draft before tearing an ACL during a workout with the Saints earlier this month.
CB Antone Exum, Virginia Tech. Exum tore his ACL in January 2013 and missed seven games that season. He missed another three with an ankle injury. He is fully healed but the injuries could cause him to slip in the draft. At 6-0, 213 pounds, he has very good size and also experience at safety.
G Spencer Long, Nebraska. Big interior lineman suffered an ACL injury in October.
QB Zach Mettenberger, LSU. He suffered an ACL tear Nov. 29 but was able to throw at LSU's pro day last week. At 6-5, Mettenberger has good size but not the athleticism Jim Harbaugh typically likes in quarterbacks.
QB Aaron Murray, Georgia. He suffered an ACL tear Nov. 25. He is expected to throw at Georgia's pro day this week.
FB Trey Millard, Oklahoma. He suffered an ACL tear on Oct. 26. The 49ers just signed Bruce Miller to a contract extension, and fullback is not a priority. Still, Millard has excellent size (6-2, 247) and runs with power and could entice with a late-round pick.
S Vinnie Sunseri, Alabama. The strong safety prospect suffered an ACL tear on Oct. 19. He went through all of the drills at school's pro day earlier this month.
