Ex-Buffalo Bills stud Roscoe Parrish was shocked to learn he had warrants out for his arrest during a traffic stop last month ... telling cops, "I live a clean life. I played in the NFL!"
The 37-year-old former receiver was busted for a routine traffic violation on Aug. 12 in Fort Lauderdale, Florida ... when cops realized he had two serious warrants out for his arrest.
One was for stalking, while the other was for writing a threat to kill ... but you can see on the arrest video, obtained by TMZ Sports, Parrish is floored when cops tell him the news.
