The Dallas Mavericks (17-12) and Phoenix Suns (14-14) will add another chapter to their stories rivalry tonight on Christmas. Phoenix is 12-8 all-time on Christmas Day, while Dallas is 3-3. Phoenix enters tonight having lost eight of its last 11 games, while the Mavericks snapped a three-game losing streak with a victory over the Spurs Saturday. The Suns will try to get out of their slump without Bradley Beal (right ankle sprain) and Jusuf Nurkiu0107 (personal reasons). However, they will be getting a big defensive piece back in Josh Okogie. For the Mavericks, Kyrie Irving (right heel contusion) will miss his ninth straight game.
