San Diego Chargers outside linebacker Melvin Ingram underwent surgery to repair a torn anterior cruciate ligament in his left knee on Tuesday.
Ingram himself confirmed the procedure, stating on his Twitter account, "Thanking God for a successful and safe surgery!!!"
In addition, the Times Union reported that the surgery was performed in Florida by Dr. James Andrews.
Recovery time is typically a minimum of six months, which means Ingram's 2013 season may not be in jeopardy.
Ingram tore the ACL one week ago during an offseason training activities session.
The 18th overall selection in last year's draft, Ingram compiled 41 tackles, one sack and five passes defensed while appearing in all 16 games and starting twice as a rookie. The 24-year-old was expected to hold down a regular role this season following the departure of veteran Shaun Phillips through free agency.
Ingram's injury prompted the Chargers to sign veteran pass rusher Dwight Freeney to a two-year contract on Saturday.
