Everton striker Victor Anichebe visited a specialist in London yesterday amid concerns he will become the third member of David Moyes's squad to postpone his scheduled return from a knee injury.
Spanish midfielder Mikel Arteta's recovery from a ruptured cruciate ligament was delayed last week due to an infection in the damaged knee, and defender Phil Jagielka underwent a minor operation on a similar injury.
Anichebe, sidelined as a result of a tackle by Newcastle United's Kevin Nolan in February, has developed "a growth of bone on his knee", according to the Everton physio, Mick Rathbone.
