The clash with struggling Everton on Good Friday has been earmarked for the player's return.
"Craig is a fortnight away but is progressing every day," said Bobby Robson today.
"The pain has gone and he's walking and doing well.
"We're in touch with Dr Steadman.
"In conjunction with what he is telling us, we're doing the right thing with Craig.
"He is allowing us to push him on a bit and see if there is any reaction. We're trying to get him fit as soon as we can.''
