Per Mavericks PR, C/PF Brandan Wright has suffered a "small, non-displaced fracture to his left shoulder." The injury was apparently sustained during practice on October 8, and will not require surgery at this time. There is no timetable set for return, but Wright's injury will be evaluated week-to-week. A little more context from ESPN Dallas' Tim MacMahon:
Brandan Wright will be in sling for at least 10 days. Will be re-evaluated weekly. Once healed, need to regain strength/range of motion.

This is somewhat of a tough blow for a Mavericks team that will need all its key players to gel well in training camp and preseason to have a shot at competing in the tough Western Conference field. As has been mentioned a number of times on this site and others, Wright was certainly one of the bright spots of last season, and he appeared to be firmly in the Mavs' plans for this season, as he never seemed to be rumored to be going anywhere other than back to the Mavs as a free agent.
While the full extent of Wright's possible rehab timeline seems a little unclear, no surgery is certainly a positive, and obviously better the injury happen now than during the season. We'll update you if and when more information is released.
