PORTLAND, Ore. (AP) Dallas Mavericks coach Don Nelson was ejected for arguing a non-call Saturday night against Portland.

Nelson was apparently angry that a foul was not called on a play involving Mavericks center Danny Fortson late in the first quarter.

Referee Michael Henderson called two technical fouls on Nelson, leading to an automatic ejection.

Nelson's son, Donn Nelson, took over in his father's absence.
