Parker (elbow) will see Dr. Neil El Attrache about his elbow Tuesday in L.A. for a C.T. scan and checkup, John Hickey of the Bay Area News Group reports.

EDGE Analysis

His visit to the doctor should shed some more light on the severity of the fracture and likelihood of his return this season. However, given the fact that the injury is in the same elbow that forced him to miss the majority of the 2015 season, it seems likely that he will miss most, if not all, of the 2016 season.
