It's possible that the Suns could get center Robin Lopez back in the Western Conference Finals, should they advance.

Heading into Sunday night's Game 4, Phoenix held a 3-0 lead over San Antonio.

Lopez got in some scrimmage work on Saturday, but Suns coach Alvin Gentry says that he needs more conditioning before he's activated.

"It's unrealistic to think Robin is going to step in and help us win one more game, but physically he is getting better," general manager Steve Kerr said.

"We're just trying to get him in position that maybe he can help at some point."
