SOUTH BEND, Ind. -- Notre Dame defensive end Stephon Tuitt was injured during Thursday's practice, going down holding his thigh/knee after an 11-on-11 play.
Coach Brian Kelly said after practice the injury isn't significant.
"We didn't see anything major there," Kelly said. "He just twisted his knee. Nothing major ... We're not concerned at all."
Tuitt laid on the ground for a minute or two and gingerly walked off the field under his own power.
Irish lose Springmann for season
Junior defensive lineman Tony Springmann will miss the 2013 season after suffering a dislocation in his knee as well as "severe" ligament damage, Kelly said Thursday. The versatile defensive lineman made 11 tackles and had one sack as a sophomore in 2012.
Defensive line coach Mike Elston rattled off Kona Schwenke, Tyler Stockton, Jarron Jones, Isaac Rochell, Anthony Rabasa and Justin Utupo as guys who are set to replace Springmann at both defensive end and defensive tackle.
"Anytime you have something like that happen you have to have guys step into those roles and I think we’ve had guys step in nicely," Elston said.
-- Freshman outside linebacker Jaylon Smith saw every first-team rep during the viewing period, with junior Ben Councell running with the No. 2 defense. The pair split time between the 1's and 2's during Saturday's practice. Kelly wouldn't commit to one starting over the other, only saying both bring different skillsets to the 'dog' outside linebacker position.
-- Austin Collinsworth ran with the No. 1 defense alongside Matthias Farley at safety, with Elijah Shumate taking second-team reps. Safeties coach Bob Elliott repeated what Shumate said about himself earlier in the week -- that he's a "work in progress" -- but emphasized both he and Collinsworth will see playing time at safety.

-- Ronnie Stanley missed practice due to a concussion, although Kelly expects him back next week. Steve Elmer filled in for him at right tackle, while Christian Lombard remained inside at right guard. Conor Hanratty returned to practice and ran with the second team offensive line.
-- Notre Dame ran a considerable amount of plays out of the pistol, and while Kelly didn't specifically mention it he did say Thursday he's beginning to implement game strategy, sets and packages for Temple into practice.
-- Kelly announced three team captains: left tackle Zack Martin, wide receiver T.J. Jones and cornerback Bennett Jackson. Martin was one of four captains in 2012, and is the 18th player to return as a captain in program history.
