According to ESPN.com, television announcer Daron Sutton has been suspended due to "insubordination." The report cited a dispute between Sutton and the club about the team's on-air dress code.

A source confirmed that dispute to The Republic, saying that while the club prefers its broadcast team to wear polo shirts adorned with the Diamondbacks logo, Sutton has lobbied to wear suits.

He made at least one veiled reference to the dispute on the air during the last game he called, an afternoon game against the Seattle Mariners on June 20.

Without going into detail, another source said the Diamondbacks have had various issues with Sutton for years.

A team spokesman said last week Sutton would not be accompanying the team on its current road trip. However, he was scheduled to call the Diamondbacks-Brewers game on Saturday for Fox's national telecast.

It's unclear if he will still call that game. Mike Connelly, the senior vice president of and executive producer of Fox Sports, did not return emails seeking comment.

Diamondbacks CEO Derrick Hall did not return a call.

The Diamondbacks have yet to give a reason for Sutton's absence.
