USC defensive lineman Liam Jimmons won't be charged after video captured the redshirt freshman knocking over a Washington State supporter after the Cougars upset the Trojans in Pullman, Wash., on Sept. 29.
Vicki I. Podberesky, the attorney for Jimmons, said she received a letter Tuesday from the Whitman County prosecutor's office declining to file charges.
Last month, the Washington State University Police Department recommended second-degree felony assault charges against Jimmons.
Video showed Jimmons, running to the locker room, knocking over a fan who had rushed the field at Martin Stadium.
In October, USC coach Clay Helton said Jimmons had been disciplined by the program, but he wouldn't provide further details.
The Whitman County prosecutor didn't immediately return a request for comment.
