Major League Soccer announced on Thursday that Minnesota United defender Brent Kallman has been suspended and fined for violating the MLS Substance Abuse and Behavioral Health (SABH) Policy by testing positive for a performance-enhancing substance.

Pursuant to the Collective Bargaining Agreement, Kallman is suspended for 10 MLS games, effective immediately, and has been fined 20 percent of his annual salary.

Kallman will serve his suspension during Minnesota's four remaining MLS regular season matches and any Minnesota United playoff matches this season, with any remaining games to be served during the 2020 MLS regular season.

The 28-year-old center back has spent his entire pro career with Minnesota United and made the jump with the team from NASL to MLS in 2017. A fairly regular starter for the team in their first two MLS seasons, Kallman has made 16 appearances (14 starts) for the Loons in 2019, the most recent being a 90-minute outing in a 2-0 win at LAFC on Sept. 1.

During his suspension, Kallman may not participate in practice or use team training facilities during the regular season or playoffs, unless rehabilitating an injury under the direction of team training or medical staff. He may not participate in tournaments, friendlies or scrimmages, and he may not attend team events, including team appearances.

Kallman will be allowed to participate in preseason training, including closed-door scrimmages, but may not participate in any other team activities during the preseason.
