The Cavaliers announced Monday that Windler (lower leg) will undergo season-ending surgery Jan. 21.
Windler's rookie season will thus begin in 2020-21, as the first-round pick wasn't able to debut for the Cavaliers after suffering a left tibial stress reaction during training camp. The forward was able to play in two games for the G League's Canton Charge in early December, but he suffered a setback shortly thereafetr and will now require a more permanent fix. A more concrete timetable for his return should emerge following the procedure, but the early expectation is that Windler will be close to full strength for the start of camp next fall.
