Ravens reserve defensive end Kapron Lewis-Moore will undergo surgery Friday in Charlotte, N.C., to repair a ruptured Achilles tendon suffered during practice Sunday, according to a source.
Dr. Robert Anderson, a renowned orthopedic surgeon specializing in treating foot and ankle injuries, will perform the procedure. Anderson is the Carolina Panthers' team doctor and performed surgery on Ravens outside linebacker Terrell Suggs' partially torn Achilles tendon in 2012.
Suggs came back from the injury to play later that season, but that's not likely to happen woth Lewis-Moore, whose injury is considered more severe. Lewis-Moore felt the tendon pop during the practice, according to a source.
Ravens coach John Harbaugh said after practice that he hadn't seen the results of Lewis-Moore's magnetic resonance imaging exam, but he noted that team doctors "seemed pretty certain about it."
During practice, DeAngelo Tyson took over the backup role behind starting defensive end Chris Canty.
Lewis-Moore missed his entire rookie season last year with a torn anterior cruciate ligament in his right knee sustained while he was playing for Notre Dame in the BCS national title game against Alabama.
He also detached his medial collateral ligament in the same knee the previous season against Southern California.
Lewis-Moore tied rookie linebacker C.J. Mosley for the most snaps with 24 during the Ravens' 23-3 preseason win Thursday against the San Francisco 49ers.
