Mike Bliss and Tommy Baldwin Racing have parted ways, effective immediately.
Bliss will replace Aric Almirola at Phoenix Racing.
Johnny Sauter will pilot the No. 36 Wave Energy Drink Chevrolet this weekend at Texas and next week at Talladega Superspeedway.
"Johnny's been with us all year long helping us out," Baldwin said. "It was short notice but he agreed to step up at Texas and Talladega."
Bliss ran five of the first seven races for Baldwin. He failed to qualify at Bristol and last week at Phoenix. TBR is currently 38th in owner points.
Sauter piloted the No. 35 entry for TBR at Phoenix and finished 41st. It was his first Cup start of the season.
