Colin Kaepernick Is Single ... And Looking for a Smokin' Hot Chick!

ATTENTION LADIES -- Are you ridiculously attractive? Wanna date a guy who just signed a $126 million contract? Well, good news ... Colin Kaepernick is officially on the market!

The San Francisco 49ers QB hit up an ESPY pre-party in Hollywood last night -- and on his way in told a reporter he's still very single and lookin' to mingle ... but only with the finest of the fine.

Dude even reveals his must-haves and his deal-breakers when it comes to the ladies.

Sidenote: Colin, who just got a "Money is the Root of All Evil" tattoo ... was sporting a gold chain last night that was SO BIG, it would've made Mr. T jealous.
