Wallace (knee) leaves game vs. Grizzlies

Boston Celtics swingman Gerald Wallace bruised his right knee in the third quarter of Monday's game against the Memphis Grizzlies and will not return.

Wallace had not attempted a field goal over 27:33, but had 3 rebounds, 3 assists, 3 turnovers and 2 steals. It was another quiet offensive night for Wallace, who attempted only one shot over 40 minutes during Boston's season opener last week in Toronto. Wallace has attempted only 16 shots in four games.

Wallace has started all four of Boston's games this season.
