Playoff Rajon Rondo will be needed more than ever.
Dallas Mavericks backup point guard Devin Harris re-aggravated his left big toe injury during Game 1 against the Houston Rockets on Saturday and is doubtful to return, reports Tim MacMahon of ESPN Dallas.
Harris missed Dallas' last game of the season with the same toe injury.
Harris has played well for the Mavericks this season, posting per-game averages of 8.8 points, 1.8 rebounds and 3.1 assists while shooting 35.7 percent from deep. He's a reliable decision maker and a heady defender.
