University of Wisconsin football coach Bret Bielema shed some more light on the attack on running back Montee Ball and the fight involving UW players that preceded it, during an appearance on a national radio show.

Speaking Thursday on The Jim Rome Show, Bielema said 15 to 20 UW football players were present at the party when the fight broke out on July 28, and two of the players involved have been disciplined. He added the police investigation into the assault on Ball is close to finished.

Bielema also reiterated Ball was not involved in the fight, which Madison police investigated as possibly leading to the assault.

"It didn't involve Montee in any way," Bielema said. "Two of my other players were involved. I've taken some actions with them and kind of let that be what it is. ... Again, Montee wasn't involved in any way, shape or form with that."

Bielema did not name the two players who were disciplined. Two players who were kept off the 105-player roster at the start of camp were sophomore linebacker Cody Byers and sophomore wide receiver Isaiah Williams. Both were added to the camp roster and begun practicing following injuries to other players.

"There was a situation where a couple of our guys — not a couple, probably 15 to 20 of our guys — were at some type of gathering and something briefly went down," Bielema said.

Bielema said police have talked to the five people they believe attacked Ball in the early morning hours Aug. 1 as he walked back to his apartment after going out for a couple of hours with friends.

Police released no new information on their investigation.

With police identifying the five people they believe were involved in the attack on Ball, Bielema said, he hopes the matter can be resolved with no further issues.

"You can never predict the future, but again, talking with the authorities ... it seems to be a point that they've got the five people who were involved, the five people who attacked Montee, had conversations with them," Bielema said.

"I hope and pray some conversations (those five) have had with law enforcement is going to deter anything from that standpoint coming up again. I think our guys are on alert, they just make themselves aware. Fortunately for us right now, I keep them pretty busy until about 11 o'clock at night, so there's not a lot of options out there."

Ball returned to practice this week in a green non-contact jersey after suffering a concussion in the assault. He has been given limited work, but impressed a group of NFL scouts this week.

"He's always fast, but he's got fresh legs now, he looks like he's going 100 miles an hour," Bielema said. "There were quite a few scouts out there that were just amazed at what he was able to do."
