DALLAS - Allen Iverson did not show up for the Big3's games in Dallas, and the league says it is investigating his absence.

The 42-year-old former 76ers standout is the biggest star in Ice Cube's three-on-three league of former NBA players. Iverson signed on as a player and coach of Three's Company for the league's inaugural season.

He hasn't been playing very much - he didn't play at all in his much-hyped return to Philadelphia - and the league said in a statement that it had no advance notice that Iverson wouldn't attend the game Sunday.

DerMarr Johnson, the team's cocaptain, took over the coaching duties Sunday.
