Pete DeBoer said Detroit native David Booth didn't come on his team's recent trip because he had a recent setback in his return to the ice.
Booth, who was concussed on Oct. 24 in Philadelphia, was cleared to start light workouts but was then stopped.
Booth will need to show that he can do normal workouts with no affects before he is cleared to skate at full strength. Booth missed Florida's game at Detroit in 2007 with a knee injury, but at least got to watch the game with family from a luxury box.
''It was a mutual decision,'' said DeBoer. ''We started to ramp up his workouts last week and had a little setback. We're kind of taking our foot off the gas and giving him some time off before we get back at it. We knew this would happen, would be part of the process.''
