Clayton Beathard, brother of San Francisco 49ers quarterback C.J. Beathard, was killed in Nashville on Friday night.
Metro Police said Beathard was one of two men fatally stabbed around 2:50 a.m. local time outside of Dogwood Bar.
Police said the altercation appears to have started when the two men were involved in an argument with a woman inside the bar. The two men were stabbed in their sides after the parties involved began to fight outside of the bar.
Beathard, 22, and Paul Trapeni III were transported to Vanderbilt University Medical Center, where they were pronounced dead.
