The Celtics  had a longer than normal practice on Tuesday at their training facility in Waltham.
Here are some nuggets from the day.
Brian Scalabrine , who already was dinged up from a mild concussion on Sunday during the win against Dallas, took a serious shot to the head from Patrick O’Bryant  and had to be taken off the court and given medical treatment. He was having pain from the light and has been ruled out for Wednesday’s game against Sacramento by head coach Doc Rivers , who added they might have to check with the Patriots for advice.
Tony Allen  looked “great” to Rivers and with Scalabrine being out, will likely return for the first time since spraining his right ankle on Jan. 4 in New York against the Knicks.
Rivers said he will remind his team that they embarrassed the Kings by 45 points on Dec. 28 in Sacramento (their lone win on the West Coast swing) because “every team in the league has pride” and they will be “out to show that that game was a fluke.”
Here is the audio version of the above.
