It appears the Cavaliers’ hopes of adding the right depth to their roster have gone out the window. Recently signed center Andrew Bogut, who began this season with the Dallas Mavericks, is out for the remainder of the regular season and NBA playoffs. Bogut, fractured his left tibia within a minute of his debut against the Miami Heat on Monday night. As noted by Tim Daniels at Bleacher Report, the loss of Bogut cuts to the core of the Cavaliers health issues.
The Cleveland Cavaliers announced Wednesday that center Andrew Bogut won’t need surgery to repair his fractured left tibia. He’s still going to miss the rest of the 2016-17 campaign, including the playoffs.
