The NBA is still investigating Thursday's altercation between Rafer Alston and Matt Barnes during the second half of the Rockets game at the Phoenix Suns, NBA spokesman Tim Frank said.

Alston and Barnes were ejected after Barnes, who led the NBA in flagrant fouls last season, ran over Alston while Alston set a screen for Tracy McGrady.

McGrady, Shaquille O'Neal, and Steve Nash received technical fouls for their roles in the ensuing scuffle.
