DALLAS -- Dallas Mavericks guard Tim Hardaway Jr. has undergone surgery for a stress fracture in his lower left leg and is expected to resume basketball activities before the start of training camp in September.

The procedure announced Thursday came after Hardaway missed the last 11 games of the regular season. The sixth-year player averaged 15.5 points in 19 games after the Mavericks acquired him in a blockbuster seven-player deal with the New York Knicks headlined by Dallas getting Kristaps Porzingis.

The 27-year-old Hardaway could start alongside 20-year-old star Luka Doncic in the backcourt next season depending on what happens in free agency, and possibly the draft. Hardaway has career averages of 15.1 points, 2.6 rebounds and 1.8 assists.

The Mavericks missed the playoffs for the third straight season, finishing 33-49 for the second time in those three years.
