The Boston Celtics will play against the Dallas Mavericks tonight in an NBA match FREE live streaming online, in HD, from American Airlines Center in Dallas at 8:30 PM ET

Dallas (40-27) earned one of its 10 wins in a 12-game span Feb. 9 in Boston, and will try to pick up its fifth in six contests as it faces the Celtics again. After dropping the opener to a three-game trip, the Mavericks responded with pair of wins, including a lopsided one over the second-place club in the Western Conference on Sunday.

Shawn Marion's 19 points on 8-of-12 shooting led a balanced effort in a 109-86 rout of Oklahoma City. Dallas had five players in double figures and four with at least 16 points while shooting 53.3 percent.

Dallas has shot better than 53.0 percent and hit 13 3-pointers in each of its two wins. Those victories have kept the Mavericks one-half game ahead of eighth-place Memphis in the West and 1 1/2 in front of ninth-place Phoenix.

Dallas has won six of seven over the Celtics (22-45) and will try to earn its third series sweep in the last four seasons. The Mavericks have also claimed three consecutive home meetings.

They appear to have a good chance at beating Boston again Monday. The Celtics have dropped four in a row and 11 of 14 after a 121-120 overtime defeat in New Orleans on Sunday.

Dirk Nowitzki is averaging 27.3 points and 10.7 rebounds in his last 12 home games against Boston. Marion has recorded double-doubles in each of his last three overall meetings, and had 11 points and 10 rebounds in last month's victory.
