Lively (ankle) has been ruled out for Sunday's game against the Grizzlies.
As expected, Lively has been downgraded from doubtful to out and will miss the regular-season finale. He has appeared in three straight and four of Dallas' last five games since returning from a two-month-plus absence. However, despite dropping a double-double Friday, Lively has yet to play more than 18 minutes in a game since his ankle injury.
