The Game -- My 49ers Would LOVE Ray Rice, But ...

With the Ray Rice sweepstakes officially underway, rapper The Game tells TMZ Sports he would LOVE to see RR on his favorite squad ... the 49ers ... but there's one big caveat.

Game -- rockin' a pretty freaky masquerade ball mask -- was leaving his birthday party at the Supper Club in Hollywood Friday night when he explained why San Fran could benefit from #27.

But while Game says he's happy to see Rice reinstated -- there are 2 big things that could get in the way of the 9ers bringing the running back to S.F.
