The Mavericks announced that forward Shawn Marion will miss at least three games with a sprain to his left medial collateral ligament (MCL). Marion will not make the road trip to New York and Charlotte.
Marion, 34, was injured while taking a shot in the third quarter of Monday night's 114-91 win over the Trail Blazers.
Marion started his third season with the Mavericks as the only holdover other than Dirk Nowitzki from the team's 2010-11 NBA Championship. Nowitzki, who underwent knee surgery in the preseason, is expected to miss the first month of the season.
