According to the order first obtained by television station WFAA, Manziel cannot see Colleen Crowley for two years.
The order says Manziel must stay at least 500 feet from Crowley's home and place of work, and owes $12,000 in legal fees.
The order was signed by District Judge Mike Sinha on Wednesday.
Manziel was under police investigation for allegedly hitting Crowley last weekend. Police in Fort Worth and Dallas said Thursday their investigations were closed and Manziel would not face charges.
But on Friday, a domestic violence complaint was filed against Manziel and Dallas police opened an investigation into the matter.
