If the Pistons are to win the championship this season, they are going to have to do it without a healthy Chauncey Billups, Joanne C. Gerstner of the Detroit News is reporting.

Billups said on Friday he wouldn't be 100 percent healthy during the rest of the playoffs.

Billups tweaked his troublesome hamstring near the end of the first half of game 2 against Boston, trying to make a move in the post. He still played well in the second half, finishing with 19 points and seven assists.
