Kevin Garnett tore into Boston's bench after they nearly squandered a 25-point lead in the fourth quarter against Portland on Friday night.

Garnett was especially emphatic with Glen Davis, grabbing him by the arm during a huddle before the starters returned to the game.

The Celtics won 93-78.

"I'll probably get real deep with him," Garnett said. "Try to understand what he's going through right now, research the problem. But Baby is frustrated a little bit with some of what we are doing. He just has to understand his role and not come outside of it."
