Brian Kelly confirmed reports of Lo Wood's season-ending Achilles' injury, which will require surgery Wednesday and should sideline the junior for 4-6 months.
The Notre Dame coach said during Tuesday's news conference that Wood suffered a non-contact injury, as Wood heard a pop while simply back-pedaling during Monday's practice.
Five cornerbacks will compete for the No. 1 field spot opposite boundary corner Bennett Jackson, Kelly said, with the distinction between the two positions fading a little for those five players.
Fifth-year safety Jamoris Slaughter will not move to cornerback, nor will first-year receiver Davonte Neal.
Redshirt sophomore right tackle Tate Nichols, who has a patella subluxation in his left knee, will likely not be available for the Navy opener. Kelly is hoping Nichols is back for Week 2 against Purdue.
