Rashee Rice is now officially a wanted man in Texas ... cops just announced they've issued an arrest warrant for the Chiefs star after he was involved in that massive car crash in Dallas last month.
Officials from the Dallas Police Dept. said in a statement Wednesday Rice is facing one count of aggravated assault, one count of collision involving serious bodily injury and six counts of collision involving injury ... this after he admitted to driving one of the cars -- a matte black Lamborghini -- that caused a huge pileup on a highway on March 30.
