Having lost two Game Sixes already this postseason, the Celtics and Head Coach Doc Rivers are viewing Friday night's battle with the Pistons as a must-win, according to The Boston Herald.
The team would love to avoid a Game Seven showdown back in Boston, which would be the third game of its kind over the last month.
"Yeah, we have (been in this position before)," Rivers said. "We have a chance to end it. But, you know, we?re playing good teams - and good teams in their place - and they?re tough to play."
The Pistons could be without leading scorer Richard Hamilton, who strained his right elbow in Game Five.
"We just have to come in and have great focus and play. We can?t worry about if we win or if we lose. We have to just focus on the game and just stay there," Rivers added.
