Notre Dame backup center Dan Wenger suffered his second concussion in 25 days, and his career could be in jeopardy.
Irish coach Brian Kelly said Wenger was concussed Tuesday, and he had a long conversation with senior Wednesday about the injuries. Wenger also suffered a concussion Aug. 13.
"We are going to have to make a decision whether or not we can put him back out on the field," Kelly said after Wednesday's practice. "We're really hesitate to do that right now.
"… That is a decision our medical team is kind of looking at right now. Dan's involved in that decision, Dan's family. We should be very cautious with anybody who's had two concussions in a short period of time.
"Right now, we have to be extremely conservative when you have a young man who hasn't had game contact and has suffered two concussions. At this point, we are never going to make any announcements on a young kid's future in the media about how important it is. Player safety is of the upmost concern. This is one that is going to have to be decided off the field, and we'll try to do that in the next couple of days."
If Wenger cannot play again, Notre Dame will likely use some combination of Mike Golic Jr. and Chris Watt as backups to starting center Braxston Cave.
"(Golic) can go in there and do a solid job, and Watt would play some center too," Kelly said. "Both of those guys have done a nice job taking reps this week."
Slaughter on comeback trail
Safety Jamoris Slaughter is recovering from a sprained ankle quicker than expected.
Kelly said Slaughter took part in warmups before Wednesday's practice a day before it was thought the junior would be able to start running.
"He had a procedure done that requires 72 hours of no walking, and he was jogging in FSA. So he is a day ahead," Kelly said. "We will see (Thursday), and I think I will have a better picture of that going into Friday."
