Yankees manager Aaron Boone said that Frazier (eye/head) is on track to return to New York on Friday and could be cleared to begin a minor-league rehab assignment next week, Bryan Hoch of MLB.com reports.

EDGE Analysis

The Yankees still haven't provided a clear diagnosis for Frazier since he first experienced symptoms of dizziness in a June 30 game before landing on the injured list a couple days later. Frazier was initially believed to be suffering from vertigo, until subsequent testing suggested he was dealing with an eye condition. The outfielder was then sent to Michigan this week to undergo neurological testing. While the latest findings aren't yet known, Boone said Frazier is doing well, and doctors have been "ruling things out." Frazier looks like he'll be cleared to perform at least some baseball activities in the coming days, and a rehab assignment could be mapped out shortly thereafter.
