Don't even think of blaming Taylor Swift! Harry Styles suffered an excruciating onstage injury in Glasgow, Scotland on Tuesday (Feb. 26) evening. As the British singer, 19, and his One Direction fans spoke to a squealing tween crowd between songs, one unseen fan showed his or her love in an unusual way: By throwing two Keds sneakers at Styles -- one of them hitting him right in the crotch.

The well-coiffed "What Makes You Beautiful" crooner immediately keeled over onstage, cupping his crotch in (mock?) pain. His bandmates Louis Tomlinson, Liam Payne, Niall Horan and Zayn Malik were suitably shocked, with one of them yelping, "Man down!"

Styles quickly recovered, jumping up and doing lunges. Styles and Swift, 22, split in early January after about two months together.

Watch Styles get pelted where it hurts now!
