Aaron Lennon is set to see a specialist to deal with a groin injury that has kept him out of action since the turn of the year.
Lennon last appeared against West Ham at the end of December, where he picked up the problem.
The England World Cup hopeful was hoped to be back last week, but a set-back has hindered his return.
Harry Redknapp is now unsure when Lennon will return and revealed the club had sent him for futher tests.
“He is seeing a specialist tomorrow,” Redknapp told Sky Sports News. “We just hope we get some good news from Aaron.
“He is going to see somebody abroad and hopefully we can get somebody who can get to the bottom of the problem for him, because he is desperate to play.
“It’s a shame for him and it’s a shame for us. We all miss him, he is a fantastic player.”
