Rangers television play-by-play man Dave Barnett said in a statement issued at 12:45 p.m. Monday that he does not expect to return to his duties this season because of medical concerns.
Barnett did not specify any diagnosis that might have caused an on-air lapse June 18 at San Diego in which he uttered a few bizarre sentences that he has since said he doesn't remember saying. He left the booth before the next game and returned home for tests that were said to be related to recurring migraine headaches.
"I want to thank everyone for your kind sentiments and words of encouragement over the last couple of weeks," Barnett said. "It has meant a lot to me during what has been a very difficult time. Effective immediately, for health reasons I will be taking an indefinite leave of absence from my broadcasting duties that I expect to last for the remainder of the season.
"I would ask that you please respect the privacy of me and my family during this time. Thank you once again for your support."
Never miss a local story.
Steve Busby, who was working on the Rangers' radio team with Eric Nadel, took over for Barnett and will remain in that capacity the rest of the season. Matt Hicks, who joined the radio team over the weekend after being hired away indefinitely from the Corpus Christi franchise co-owned by Nolan Ryan, will continue to work with Nadel.
