Fairfax County police say the 29-year-old Haynesworth and his attorney appeared at a police station Saturday morning. Haynesworth signed a summons warrant charging him with assault and left.
He's scheduled to appear in court on March 31.
Police say a 38-year-old man told investigators he was assaulted by the driver of a pickup truck who was tailgating him on Feb. 2. The driver was later identified as Haynesworth.
Simple assault is punishable in Virginia by not more than a year in jail and a fine of $2,500 or less.
