Marco Schallibaum's tumultuous first season with the Montreal Impact continues.

After Schallibaum received an automatic one-game ban for being sent off in Montreal's win over DC United last Saturday, Major League Soccer suspended the fiery Swiss manager for an additional game and fined him $5,000 US Friday "for his repeated misbehaviour."

Schallibaum and United manager Ben Olsen engaged in their heated confrontation following a hard aerial challenge between DC's James Riley and Montreal's Justin Mapp, which sent the Impact player clattering into the midfield camera.

Olsen and Schallibaum were sent off while Riley was issued a yellow card. Olsen had his automatic one-game suspension and fine rescinded on Friday.

"I spoke for my player, Justin Mapp, because he fell down into the camera. Because he's my player, I wanted to go see what happened because it's a very dangerous situation," Schallibaum said at the time. "I was out a little bit from my zone."

Schallibaum has been ejected from games three times this season. He also served a one-game suspension for stepping on the field in a game against the Colorado Rapids.

Schallibaum will be suspended for Montreal's home game against Houston on Saturday and its road game in Philadelphia on Aug. 31.
