Jose Mourinho admits Manchester United are uncertain about the severity of Eric Bailly's latest knee problem after the defender was forced off against Crystal Palace.
The Ivory Coast international started at right back in United's 2-1 win on Wednesday night but had to be substituted shortly after half-time with a knee injury.
Bailly made his first start in almost two months since he injured ligaments in his right knee during United's 4-0 drubbing against Chelsea on October 23.
Mourinho confirmed after the match at Selhurst Park that Bailly's latest injury was to his left knee but is awaiting test results before determining how long the defender will be out for.
"The only thing I can say is that it is not the same knee," Mourinho told MUTV.
"He had an injury in the right knee and he recovered fantastically well. Now it is the left knee. I don't know really what he has, but let us see and wait.
"He could resist for so long. I would say for about 75 minutes he could resist. He is a special guy and his pain level is really high."
The 22-year-old has been a huge success since joining United in the summer from Villarreal for a fee of £30m, immediately establishing himself as Mourinho's first-choice centre-half.
Bailly showed his versatility against Palace by filling in for the suspended Antonio Valencia at right-back before being replaced by Italian international Matteo Darmian.
In recent weeks, Phil Jones and Marcos Rojo have forged a steady partnership at the heart of United's defence with Bailly and Chris Smalling both out injured.
Bailly's latest injury puts his participation in the upcoming Africa Cup of Nations in question.
He is due to depart for Gabon early next month, ahead of the Ivory Coast's opening match of the tournament against Togo on January 16.
