Shawne Merriman -- Johnny Manziel Should Stay Far Away From SB 50

Shawne Merriman has some advice for Johnny Manziel ... don't show face at Super Bowl 50 and get your mind right.

Our photog spoke with Shawne outside the Sports Illustrated party Friday in San Francisco and he dished out some tough love for the QB. The main point being, stay out of the spotlight.

Take a look at the clip, he even calls out the NFL.

Merriman is just one of many NFL'ers to offer advice to the QB, Brandon Marshall was vocal earlier this week about Johnny's recent struggles.
