Dan Wenger's career in question

SOUTH BEND, Ind. -- Notre Dame fifth-year senior Dan Wenger has suffered his second concussion in less than a month, coach Brian Kelly said after practice on Wednesday.

The injury leaves Wenger, who lost his starting job at center this fall to junior Braxston Cave in part because of a concussion, to decide whether he can continue his college career.

"Dan and I had a long conversation today," Kelly said. "You know he's had these concussions and it's really … you know, we're going to have to make a decision as to whether we can put him back on the field. We're really hesitant to do that right now. He had another concussion yesterday. So that's his second concussion in a matter of, what, three weeks. That's a decision that our medical team's kind of looking at right now."

The 6-foot-4, 298-pounder was not available for comment. Wenger started all 13 games at center for Notre Dame in 2008. Last year he moved to guard and appeared in eight contests, including one start against Navy.

Mike Golic Jr., currently listed behind Trevor Robinson at right guard, will switch to center behind Cave.

"Yeah, [Golic] would come in and I got a lot of confidence in him," Kelly said. "He can go in there and do a solid job and [Chris] Watt would play some center too."

For now, Wenger's future hangs in the balance.

"Dan's involved in that decision, [and] Dan's family," Kelly said. "We should be very cautious with anybody that's had two concussions in a very short period of time. Right now, we have to be extremely conservative when we have a young man that hasn't had game contact and has suffered two concussions. … Player safety here is of the utmost concern. This is one that's going to be … have to be decided off the field and we'll try to do that in the next couple of days."
