The bruised left thigh that sidelined Steve Nash for the last 2 1/2 games is no longer a problem, but he twisted his back when backup point guard Leandro Barbosa stepped on his foot. Nash was in obvious discomfort after more than an hour of treatment.

"It was painful," coach Mike D'Antoni said. "We'll see if he can get the spasms out and he might be fine, or he might have to take a few days off."
