Floyd Mayweather is at it again.

The boxing star, a noted gambler who is never shy to open about his winnings, appears to have taken in a nice sum this week thanks to the Michigan State Spartans and the Oklahoma Sooners.

After Michigan State's 24-20 win over Stanford Mayweather, a Grand Rapids, Mich., native tweeted that he had won $112,500.

Then, following Oklahoma's 45-31 upset of Alabama in the Sugar Bowl, Mayweather tweeted this photo of another winning ticket. The Sooners' 31-17 halftime advantage made Mayweather $102,500 richer.

All told, Mayweather won $215,000 this week. Of course, Mayweather never posts his losing tickets, and assuming he does sometimes pick the wrong team, he may have lost some money too. And while $215,000 is a fortune for most people, this is just a drop in the bucket for Mayweather, who is one of the world's highest paid athletes and has more than $120 million in a checking account.
