A six-hour arbitration hearing yesterday ruled that an Independent Commission had been correct to uphold Carroll's straight red and ban for violent conduct against Swansea after he caught Chico Flores with a swinging arm and the Swansea defender went down clutching his face.
Allardyce said: "I'm frightened of going near him. He is hugely frustrated and angry and disappointed in this situation.
"It is best to leave him well alone and let him get over it. Simulation has been allowed to win."
