The two Wagga rivals added a new chapter to their history after Chris Maher's send off threatened to spill over the sidelines.

Maher was given his marching orders by referee Sean Byatt for a high shot on Darryl Charles in a fiery second half.

The hit left Charles with a suspected concussion and it didn't stop him, and a number of his friends, trying to remonstrate with Maher in the dressing shed.

Brothers president Mitch Dunn was disappointed by how the events unfolded, especially with how drawn out the drama was and the language used.

"It is not something we want to be as a club," Dunn said.

"There was a lot of lot of yelling and carrying and no doubt I'm sure some people in the crowd felt uncomfortable.

'"It was not a good start."

However Dunn also believes Charles was not in a good head space after the high shot.

"I don't think he knew what he was doing or was fully coherent," Dunn said.

"He kept on asking what happened and who got him.

"How he reacted is probably how he would react normally but I think it might have stopped after the initial thing, not keep going.

"It's embarrassing.

"I rang Mahery and apologised to him on behalf of the club as it is not something we stand for."

Maher played for Brothers last season before making the move to their Group Nine rivals.

Kangaroos president Peter Hurst believed the whole incident soured the club's 34-16 win to start the season.

"It was a disappointing end to a good win," Hurst said.

Maher and his young family had to be escorted away from the ground.

He will await the match review to see if he faces any charges ahead of a clash with Tumut at Equex Centre on Sunday.

Dunn also expects Charles to be on the sidelines when Brothers look to respond to their loss against Young on Sunday.
