With the Cleveland Browns in serious quarterback trouble, Johnny Manziel says one thing's for sure -- they're definitely not calling him.
A sober Manziel was leaving Mr Chow in Bev Hills Monday night when he kept it 100 about his chances of going back to the Browns ... "I doubt that'll happen."
Still, Johnny says with a smile ... "I wish them the best."
JM doesn't seem too concerned -- telling TMZ Sports he's focused on going back to school anyway.
By the way, Manziel's wearing an L.A. Rams hat -- they could use some QB help!
