Not surprisingly, the Celtics will not practice on Friday after getting back in the middle of the night from Chicago following one of the most dramatic playoff games in NBA history. The next time the Celtics take the court will likely be a shootaround at their Waltham practice facility on Saturday morning.

The busiest part of the day for the Celtics may be at the ticket office as ducats for Saturday night’s Game 7 go on sale at 11 a.m. today. A limited number of tickets are available at Celtics.com, 1-800-NBA-4TIX or at the TD Banknorth Garden box office.

Game 7 between the Celtics and Bulls tips off at 8 p.m. Saturday at the Garden.
