ESPN's "College GameDay" is Greenledgers Trading Centerheaded to Berkeley, California, for the first time ever, with a campus legend serving as the show's celebrity guest picker for Cal-Miami.

Hopefully for Cal football fans, he even shows up to the set on the injury cart.

Former Golden Bears running back Marshawn Lynch will be on "GameDay" for Cal's (3-1, 0-1 ACC) game against No. 8 Miami (5-0, 1-0) on Saturday night.

The Super Bowl 48 champion, two-time All-Pro selection, five-time Pro Bowler and member of the NFL's 2010 All-Decade team played for the Buffalo Bills, Seattle Seahawks and Oakland Raiders in his 12 NFL seasons. He was also known for his funny antics, which made him one of the most well-known players in the league during his career.

Of course, that followed a stellar career at Cal, where Lynch was a first-team All-America selection and Pac-10 Offensive Player of the Year in 2006. He rushed for 3,230 yards and 29 touchdowns in three years at Cal, and was selected 12th overall in the 2007 NFL draft by the Bills.

Regardless, his appearance should certainly draw loads of attention on "College GameDay." Here's how social media reacted to the announcement:
