NYPD Blue S09E19 - Low Blow

Cops ridicule Clark when they think he is backing out of the big boxing match against Laughlin. Meanwhile, a fireman suspected of raping his estranged wife is also suspected of brutally raping another woman, and a phony physician is found dead in his car. Clark and Laughlin's fight is cancelled by the event organizer, but when they convince him the fight is not a grudge match, he reinstates it. At the fight, Clark knocks out Laughlin, despite taking a nasty, deliberate low blow from his angry competitor. Afterwards, Ortiz arrives at Clark's door to thank him for his chivalry, and Clark and Ortiz spend the night together.
