Northwestern will be without at least three projected starters when it opens spring football in the Big Ten with the first of 15 practice sessions Wednesday in Evanston.
The Wildcats announced Monday that three projected starters will miss the spring session with injuries: cornerback Nick VanHoose, middle linebacker Damien Proby and offensive tackle Jack Konopka. Several other players who filled reserve roles in 2012 but could claim starting jobs in 2013 also are out, including offensive tackle Paul Jorgensen, wide receiver Kyle Prater, defensive tackle Will Hampton, defensive end Deonte Gibson and guard Matt Frazier.
All 13 players out for the spring are expected back for fall camp and the season. Most are recovering from postseason surgeries.
VanHoose missed three games late last season with a shoulder injury, so his absence for spring isn't a major surprise. Prater also didn't look 100 percent healthy in 2012. Konopka started at right tackle in 2012 and could be moved to the left side to replace the graduating Patrick Ward.
Both Proby and Konopoka started all 13 games last season.
Both Jorgensen and Frazier played behind offensive linemen who graduated following the 2012 season, so their absence this spring should ramp up the competition at those positions.
Both Gibson and Hampton, who started three games last season, figure to be in the mix for starting defensive-line positions, although they'll have to make up for lost time this summer.
Northwestern practices nine times before finals and spring break in mid-March. The Wildcats return for four more sessions before wrapping up with their spring game on April 13.
