Coulter, who has been in radio and television for 42 years, joined The Zone when it came on the air in August 2011.
Sanderson, the former
basketball coach, joined Coulter as his partner last July.
"I want to thank all of the listeners and all of our sponsors for their support," Coulter said this afternoon. "They've been there since we started."
The cancellation of "Straight Talk" was the first major programming change since the sale of the Cox Media Group, which owns The Zone, to Summit Media became official on Friday.
The station hopes to hire Paul Finebaum to fill that slot. Finebaum has been in talks with The Zone and with rival WJOX 94.5 FM since his contract with WJOX owner Cumulus Media expired on Jan. 21.
The new SEC Network, which was announced last week, is also believed to be making a bid to hire Finebaum.
