Pilar Sanders has been arrested for domestic violence after allegedly attacking Deion Sanders in their Texas home this afternoon.
According to the Colin County Jail website ... Pilar was booked for "assault family violence" -- a misdemeanor.
As TMZ reported, NFL Hall of Famer Deion claims his estranged wife, Pilar and her friend jumped him in his bedroom earlier today. Deion says two of his sons witnessed the alleged attack.
Although Pilar and Deion are going through a bitter, BITTER divorce ... they are still living together in their suburban Dallas home.
Deion told TMZ Pilar had been taken to the hospital immediately after the incident -- claiming she needed medical treatment -- but she is now in police custody.
Deion claims he didn't harm Pilar, and only "defended" himself until he was able to call police.
