49ers coach Mike Singletary lashed out at CBS 5 sports director Dennis O’Donnell during a weekly “Coach’s Corner” TV segment Thursday night.

Singletary refused to answer questions O’Donnell posed about the controversy surrounding quarterback Alex Smith’s ability to get plays relayed to him from offensive coordinator Jimmy Raye, and the fallout it has created.

Jason Cole of Yahoo! Sports reported this week that there’s growing tension between the 49ers’ coaching staff and players over play-calling issues.

UPDATE: CBS 5 (KPIX-TV) pulled the video from its website late Friday afternoon.
