Carroll was suffering from tiredness and a minor ankle which is believed to be related to a knock he took in training.
But a source confirmed this morning that the big fella will be back on duty for the clash in Wales.
He said: “He’d played all over Christmas and suffered a minor injury in training but he will be okay for Swansea.
“We will check Alex Song before the game but we are obviously hopeful he will also make the match following his trip to Cameroon.”
