Fergie made a personal call of support to the former United defender urging the 22-year-old not to miss out on England duty.
Shawcross has been struggling, after his late tackle left Arsenal midfielder Aaron Ramsey with broken tibia and fibula in his right leg.
Pulis revealed: “Sir Alex rang Ryan after the game (Carling Cup Final) on Sunday to give him his support and told him that he shouldn’t miss out on England duty.
“These things do happen, unfortunately, and Sir Alex still thinks a lot of Ryan after having him for so long at Manchester United.
“He knows him as well as I do and knows he is not the sort of player to go out to deliberately hurt anyone.
“Sir Alex had obviously seen the incident and believed, like I do, that it was an accident.
“He told him he will get over it, even though he knows he’s hurting now.
“Ryan really appreciated the call and it’s given him a bit of a lift at a very difficult time.”
