The trend of physical confrontations continue on the set of the new boxing reality show - "Knockout." The show is set to debut on NUVOtv.

The show will feature fighters from the 140, 147 and 154-pound weight divisions. Trainers Floyd Mayweather Sr., Yoel Judah, and Ruben Guerrero will lead the fighters into competition against each other and the winners will then step up and fight a top 20 contender or a blue chip prospect.

BoxingScene.com was advised that an altercation took place between welterweight contender Tim Coleman (19-4-1, 5KOs), who was brought in as a contestant on the show, and veteran matchmaker Rick Glaser, who is part of the "Knockout" staff as the Executive Director of Competition.

From what BoxingScene has learned, Coleman's wife contacted Glaser, via Facebook on Wednesday, and advised him that her husband was having some legal issues with the police.

Coleman, enraged over the Facebook conversation, unexpectedly attacked Glaser and had to be physically restrained by several individuals. As the present, Coleman is still involved with the show but he's on a "behavior watch."

When reached for comment incident, Glaser said the following:

"He bumrushed me and was going crazy. I had already hurt my back earlier when I slipped on the gravel in the parking lot. I'm still walking funny right now. He just bumrushed me as I was coming up, out of the chair. I was slow in doing so because my back was so bad. By the time I looked he was already on top of me. A bunch of people broke it up. I had no idea what was going on. I had no clue. In my 22 years of matchmaking, I've never had anything like this happen to me before. It's reality TV and it's fighters, anything can happen" Glaser told BoxingScene.com.

This marks the third incident in less than a week. In the last few days, trainers Floyd Mayweather Sr. and Ruben Guerrero had two separate physical confrontations on the show's set.
