BOZEMAN, Mont. (AP) — The parents of a former Three Forks High School football player have filed a lawsuit against the school district claiming their son suffered a life-altering brain injury after sustaining at least two concussions over a period of six days.

The Bozeman Daily Chronicle reports Kim and Joseph Rouchleau filed the claim in District Court in Bozeman on April 12, alleging the coaches were negligent when they sent Michael Rouchleau back in to practice despite his doctor's orders that he not participate in contact activities for 11 days.

The lawsuit claims that six days after the initial concussion, Rouchleau was tackled by a linebacker and knocked unconscious.

Helena attorney David Dalthorp said he believes it will become apparent that many of the allegations in the complaint are not true.
