Cardiff City have lost their appeal against Glenn Loovens' red card against Preston on Saturday.
Loovens felt aggrieved by his sending off at Preston
Centre-back Loovens was dismissed after appearing to bring down Preston striker David Nugent just outside the box.
Loovens travelled with the squad to Plymouth for Tuesday's league match, but the FA of Wales decided that the referee's decision was correct.
"Glenn has been punished for being stronger than their boy. It was shoulder to shoulder," said Jones.
"Anywhere else on the pitch, as the ref said, he wouldn't have given a caution."
