A 20-year-old man was injured as a result of the fight outside downtown Aug. 12, Regina Police spokeswoman Elizabeth Popowich said Friday.
Boogaard, 24, was arrested Aug. 24. He is to appear in court Sept. 20.
"Derek denies the allegation and will defend himself in any legal proceeding that may take place as a result of the allegation," the Wild said.
The Wild signed Boogaard to a $525,000 one-year deal this summer. The 6-foot-7, 250-pounder appeared in 65 games for the Wild last season, collecting 158 penalty minutes along with two goals and four assists.
Boogaard lives in Regina, where he spent part of his junior career in the Western Hockey League.
