Johnny Ludden of the San Antonio Express-News reports: Tonight, as the San Antonio Spurs go against the Phoenix Suns in Game 2 of their first round series, their frontline will be a little thin.

The Spurs, who are down 1-0 in the best-of-seven series after a devastating loss on Saturday, will be without Kevin Willis and most likely David Robinson.

Willis got suspended for tonight?s game after elbowing Phoenix center Scott Williams in the throat toward the end of the second quarter of Saturday's game. Willis was given a flagrant 2 foul and ejected from the game.

Players normally receive an automatic one-game suspension after they accumulate three flagrant points in the playoffs. Willis received two flagrant points for the foul, but NBA officials suspended him because he hit Williams above the neck.

Robinson is doubtful after banging his knee taking a fourth-quarter charge from Stephon Marbury.

Robinson?s knee stiffened as the game continued. He underwent an MRI on Sunday afternoon and was given a therapeutic injection. He will be evaluated this morning, but team officials do not expect him to play.

Malik Rose is expected to start in Robinson?s place.

With the injuries, the Spurs know they need to come up big tonight or risk going down 2-0 in the series.

"We can't be scared just because we lose one," guard Tony Parker said. "It was a big win for Phoenix. Now we have to concentrate. Me, (Stephen Jackson) and Manu (Ginobili) are ready to take that challenge."
