The tension that has been building between the teams throughout nearly boiled with 18 seconds to play.

The Suns, who trailed by as many as 11 points, had taken the lead for the first time in the second half on consecutive behind-the-back feeds from Steve Nash to Amare Stoudemire that mad it 100-97 with 32 seconds to play.

As Nash started to bring the ball up the court after Manu Ginobili missed the Spurs' fourth straight shot, San Antonio's Robert Horry hit him with a forearm that knocked him into the scorers' table and had players from both teams rushing to the scene.

Phoenix's Raja Bell tried to get at Horry as did Nash after he jumped to his feet.

Horry was given a flagrant foul and was ejected. Bell was given a technical foul. A free throw by each team made it 101-98. The Suns kept possession and Nash added another free throw with 16 seconds to go.

Shawn Marion added two free throws with 7.4 seconds to go.

Game 5 is Wednesday night in Phoenix and it's possible there could be suspensions from the league for players leaving the bench after Horry fouled Nash.

Stoudemire led the Suns with 26 points, while Nash had 24 points and 15 assists.

Tony Parker led the Spurs with 23 points and Tim Duncan had 21 points and 11 rebounds.

The increasingly hostile series has been marked by bumps, bruises and harsh words. A gash across Nash's nose required six stitches after a collision with Parker in Game 1 and Ginobili got a bloodied and bruised eye in Game 3 on a drive to the basket.

Last week, Stoudemire called the Spurs a "dirty team" and targeted Bruce Bowen and Ginobili in particular. He said Bowen purposely kicked him in the Suns' Game 2 win.
