Cavaliers guard J.R. Smith has thumb surgery, to miss 12-14 weeks

Cleveland Cavaliers guard J.R. Smith will miss 12 to 14 weeks after having surgery to repair a “complex fracture” of his right thumb, the team announced Friday.

Smith suffered the injury while swiping down on Milwaukee’s Giannis Antetokounmpo during the first half of Tuesday’s 114-108 overtime road victory against the Bucks.

The 13-year veteran, who signed a four-year, $57 million extension with the Cavs in the offseason, was averaging 8.6 points on 33.7 percent shooting this season — the second-worst scoring average and worst shooting percentage of his career.
