NASHVILLE, Tenn. (KGO) -- The man accused in the stabbing death of Clayton Beathard, the younger brother of 49ers backup quarterback C.J. Beathard, has been arrested.

Police say the fight started when Mosley made an unwanted advance at a woman that was at the bar with Beathard.

It spilled outside, and that's when Beathard was stabbed to death along with another man during the fight.

Clayton was the starting quarterback for Long Island University and just finished his junior season.
