One of the participants will be Jesse Plemons, who plays lovable sidekick and football player Landry on Friday Night Lights.
The Mart, Tex., native will be on hand at the event for pictures and autographs.
Plemons' mother is a teacher in Waco who works with children with autism.
The walk is at the Dell Diamond in Round Rock, Tex., the Austin American-Statesman reports.
Area residents should consider joining Jesse Plemons in this effort to raise money for a good cause - and maybe meet him, too!
