S2·E37 Slab Happy

Punch-drunk former boxer Kid Dakota still carries a torch for gold-digging his ex-wife Julie. The Kid got into a fight with Julie's current husband at their restaurant (which used to be his) and vowed to kill him. When the husband turns up dead a few hours later, the police have an open and shut case. Mike, however, thinks Kid's been framed by someone else who wanted the current husband dead.
