INTERIM Manchester United boss Ralf Rangnick has confirmed Luke Shaw will be out of action for "two or three weeks".
Shaw, 26, is set to go under the knife to have metal bolts removed from his leg that were initially put there following his horror leg break in 2015.
Shaw was forced off at half time in last weekend's 1-1 draw against Leicester.
The England star is suffering complications related to the bolts that were inserted into his right leg during the original surgery after his grisly injury.
Rangnick told reporters on Friday ahead of the weekend's trip to Everton: "Cristiano is back again but Luke is still injured.
"We had to take him off at half-time [against Leicester] and he is having problems with his leg where he had the operation back in 2015.
