According to Scott Souza:
The drama came about 90 minutes before gametime when Tony Allen had an argument with Boston Globe reporter Marc Spears in front of about 30 media members and team staff in the locker room. No other players were in the locker room at the time.
It’s unclear what started the confrontation, but the Globe was among the outlets that reported on death threats Allen had received while in his hometown Chicago this series.
Allen was heard telling Spears: “Don’t let me hear my name coming out of your mouth,” while Spears didn’t back down in the verbal jousting. Both eventually left the locker room with Allen mumbling about Spears, but saying he would be fine as long as he didn’t have to deal with the reporter.
