Two significant helmet-swinging incidents have marred recent football practices in both college and the NFL. At Appalachian State University, a player struck a teammate with a helmet during a practice scuffle, leading to internal discipline and a wave of criticism on social media. Similarly, Seattle Seahawks' wide receiver DK Metcalf swung a helmet at teammate Tre Brown, accidentally hitting K'Von Wallace, during a heated training camp session captured on live TV. Multiple fights characterized the Seahawks' practice, prompting coach Mike Macdonald to address the team and urge restraint. Both incidents have stirred discussions on player discipline and the risks of such violent behavior in sports.
