Mavericks guard sidelined by right knee soreness

In a pre-game meeting with reporters, coach Jason Kidd said the team is taking a cautious approach with Exum’s recovery. He indicated that Exum will be out for an extended period, but didn’t speculate on how long it might be. This is the first time anyone from the team has provided specifics on the injury that has affected Exum since training camp began.

Kidd added that the Mavs are taking a “long-term view” with Exum’s health and explained that the injury has “delayed his preparation for the start of the season,” tweets Grant Afseth of Dallas Hoops Journal.

Injuries have been a career-long issue for Exum, who only appeared in 20 games last season due to right wrist surgery and a broken left hand. He was still an effective player when healthy, making 13 starts and averaging 8.7 points and 2.8 assists in 18.6 minutes per night.

Exum reached an agreement in early July to re-sign with the team on a one-year, minimum-salary contract. The deal wasn’t finalized until September 1 because Dallas had to open a roster spot and clear up room under its second apron hard cap. That happened when the Mavs waived and stretched former first-round pick Olivier-Maxence Prosper in late August.

Dallas had been hoping for better health from the 30-year-old combo guard, as Kyrie Irving is still recovering from a torn ACL and his return date remains uncertain. In addition, Brandon Williams is dealing with a hamstring strain he suffered early in training camp.

If Exum’s absence appears to be prolonged, it could improve the chances for Dalano Banton (Exhibit 10 contract) or Dennis Smith Jr. (Exhibit 9 deal) to earn a roster spot.
