Christian Lombard out after surgery
Lombard, a redshirt senior who started the last two seasons at right tackle and right guard, respectively, underwent surgery Thursday on a dislocated right wrist that he suffered during the Irish's third spring practice on Wednesday.
Mahone, a redshirt sophomore, had surgery Thursday on a right foot fracture.
Conor Hanratty figures to receive the majority of reps with the first-team offensive line in Lombard's place.
