The Minnesota State High School League said it asked for additional information Monday in its investigation of an on-field fight between soccer players from Fridley's Totino-Grace High School and Brooklyn Park's Prairie Seeds Academy.

The league plans to conclude its investigation Tuesday and issue a definitive statement, according to a news release.

The fight took place Oct. 18 as the game, a 2-1 Prairie Seeds victory that earned the school a trip to the Class 1A state tournament, ended at Maple Grove High School's stadium.

Video footage shows a Prairie Seeds player appearing to be pushed before he turned around and punched the opposing player. Other players and officials swooped in as more punches were thrown in a chaotic scene on the sideline.

High school league executive director Dave Stead said Monday that the league "hasn't ruled anything in or out" in terms of player suspensions.

Maple Grove Police Capt. Keith Terlinden said Monday that his department's investigation is ongoing and separate from the MSHSL's.

Prairie Seeds, the 2010 state champion, opens state tournament play Friday.
