49ers rookie offensive tackle Mike McGlinchey dedicated his "My Cause, My Cleats" shoes to his little brother, Jimmy.
Jimmy was diagnosed with autism when he was 18 months old, so McGlinchey wanted to represent Autism Speaks, an organization that sponsors autism research and conducts awareness and outreach activities aimed at families, governments and the public.
"Autism is nothing that's a downgrade to your child," he said in an interview with NBC Sports Bay Area. "It's not a burden. It's something to be embraced and not deflected."
Puzzle pieces are printed along McGlinchey’s cleats, which he’ll wear in Sunday’s home game against the Denver Broncos.
"It's kind of the logo so you can really make that look really cool," he added.
The My Cause, My Cleats campaign is part of a collaboration between the NFL and players. The players will represent hundreds of charitable organizations that focus on a vast array of causes that will be represented on their customized cleats.
