Human Factors; Procedure
Aircraft X was instructed to circle and overfly the airfield for a left base. Aircraft X joined the left downwind for circle and another aircraft was on final. Aircraft X would have had to turn very close inside of the aircraft on final. I canceled his approach clearance while in the downwind and turned him out to a 240 heading and climbed to 4;000 feet. Aircraft X went into the 3;600 foot Minimum Vectoring Altitude at 2;300 feet.
A CHA Tower Controller reported they had to vector an aircraft out of the pattern and it flew below the Minimum Vectoring Altitude.
