Watch: American footballer joins cheerleaders for halftime routine

Arizona Rattlers fans were in for a treat during a recent halftime show, after an American footballer joined the squad's cheerleaders for an incredible routine. A video of the performance, which has gone viral since being posted online earlier this week, sees the player throw some seriously sharp shapes - including twerking and even a full splits - to the delight of the cheering crowd.

Yep, it turns out that the mystery man was in fact a professional dancer called Oscar Hernandez, who's worked with hip-hop stars like Flo-Rida, Busta Rhymes and T-Pain in the past. Even so, this hilariously on-point performance is giving us life on this grey Thursday morning.
