US football player has big thanks for 1D star after this performance!

National Football League player Michael Sam has thanked One Direction star Harry Styles for his support after he performed in his jersey.

Harry was singing on stage in St Louis, Missouri, when he wore Michael's Rams blue and yellow shirt with his name and number on the back.

When Michael, who became the first openly gay man drafted into the NFL, caught wind of what Harry was wearing, he hit Twitter to thank him for his support.

The St. Louis Rams also tweeted a shot of Harry wearing the jersey on stage at the band's show.

Earlier this week, a US TV outlet was forced to release a statement saying it regretted a controversial report that discussed the showering habits of Michael and whether he was avoiding the shower when teammates were present.

Back in March, the 24-year-old broke down in tears as he was told he had been drafted to the St Louis Rams in the NFL draft, becoming the first openly gay player in the league’s history.
