Cavs' Wallace plays in opener against Pistons (AP)

Cavaliers center Ben Wallace returned from a knee injury and played in the postseason opener against the Detroit Pistons. Wallace missed the final two games of the regular season with a strained patellar tendon in his left knee. He has been limited in practice, but Cavs coach Mike Brown dressed Wallace for Game 1 on Saturday and inserted him in the final two minutes of the first quarter.
