The Red Devils manager suggested the Swans skipper Ashley Williams could have killed Robin van Persie when he attempted a clearance in the 1-1 draw with the ball hammering the Dutchman in the back of the head.
Ferguson feels Williams should be banned for a long time for the act but Laudrup played down the United gaffers anger by suggesting the adrenalin from the match was still pumping.
"I did not see it at the time as there were a lot of players involved, but I saw it afterwards,” said the Dane.
"I don't think he (Ferguson) meant literally killing him.
"Things happen in a game and I am sure Ashley and Van Persie shook hands at the final whistle and we move on.
"When your pulse is on 180 then you can say things during the game you don't mean but then afterwards it is back to normal."
