Marshall has filed a lawsuit against Conference USA to expedite its exit from the league so it can join the Sun Belt this summer, according to a copy of the case filed Tuesday.
Earlier this month, Marshall, Old Dominion and Southern Miss announced their plans to terminate their memberships in Conference USA on June 30 to become members of the Sun Belt. In mid-February, Conference USA released its 2022 football schedule, which included all three schools, and pledged to "exhaust all necessary legal actions" to ensure the outgoing members would participate this fall.
"For more than two months, Marshall University has attempted to reach a resolution with Conference USA regarding our decision not to participate in the league after this academic year; however, no progress has been made," a Marshall athletics spokesman said in a statement to ESPN.
