Jim Brass makes a quip "if you're wearing a badge, I'm playing left wing in the NHL" to one of the guys who beat the cab driver. Though he doesn't play professionally, Paul Guilfoyle is actually a frequent player in celebrity hockey tournaments.
Although credited, Nick Stokes (George Eads) does not appear in this episode. Additionally, Catherine Willows (Marg Helgenberger) is only in one scene.
