It has been reported for weeks that Viduka had played his last game for Newcastle, but Shearer has not ruled out a return.
Alan Shearer: "Mark Viduka has trained for the majority of the week and will travel with us.

"He has trained well. He obviously has got a huge amount of talent and we believe if we can keep him fit, he will play a big part in helping us."
Peter Lovenkrands could return to the squad after recovering from the chest infection which left him fighting for breath during the 2-0 home defeat by Chelsea, although Jose Enrique remains a doubt with a knee problem.
In addition, midfielder Joey Barton is expected to return to full training next week and could come into contention for the home clash with Portsmouth on April 27.
