Missouri quarterback Shawn Robinson, through the school, has filed a waiver for immediate eligibility with the NCAA, according to sources, alleging mistreatment during his time at TCU.

TCU is contesting the grounds that waiver is supported on, according to sources.

The NCAA has yet to make a decision on the matter, but it is expected soon.

From Missouri’s perspective, an eligible Robinson would give the Tigers an experienced backup behind Clemson transfer Kelly Bryant this fall. Plus, if Robinson plays in four or fewer games, he’d remain eligible for a redshirt season in 2019.

The NCAA waiver for immediate eligibility is confidential and the specific nature of what Robinson’s claims pertain to is unknown as far as the alleged mistreatment at TCU.

Robinson injured his left shoulder during the TCU-Iowa State game on Sept. 29, and started in TCU’s next game against Texas Tech on Oct. 11 and again in the Oklahoma game on Oct. 20.
