Source -- Mavs optimistic Kyrie Irving will be OK by training camp - ESPN

Dallas Mavericks guard Kyrie Irving underwent surgery to repair a broken left hand, the team announced Tuesday.

Irving suffered the injury while training earlier this month.

While the Mavericks did not provide a timetable for Irving to be cleared to return to basketball activity, a team source expressed optimism that he would recover in time to participate in training camp.

Irving, an eight-time All-Star, played an essential role in the Mavericks' run to the NBA Finals. He averaged 22.2 points and 5.1 assists per game during the postseason.

The 32-year-old Irving, who averaged 25.6 points and 5.2 assists during the regular season, also played a significant role in recruiting Klay Thompson to join the Mavs in free agency.
