New reports have surfaced alleging Florida State quarterback Jameis Winston was involved in a point shaving scheme to help an old high school teammate win a $5,000 bet.

According to the report, Winston tanked the 1st half of the FSU vs. Louisville game on October 30th ... after his buddy Chris Rabb allegedly placed a bet for Louisville to be winning at halftime.

Winston's play in the 1st half was atrocious ... and FSU was down 21-7.

FSU eventually came back and won the game -- but according to the report, the final score had no bearing on Rabb's bet.

FYI -- point shaving is illegal and punishable by up to 5 years in prison.

So far, it's unclear if law enforcement is investigating -- but we're working to find out if that's the case.
