The United skipper missed the 3-0 Boxing Day victory over Sunderland at Old Trafford due to a thigh injury he felt during training on Christmas Day.
Boss Jose Mourinho does not expect him to be fit for the New Year’s Eve home clash against Middlesbrough – but hopes the 31-year-old will be fit again soon.
“Honestly, I don’t think so,” Mourinho said when asked if Rooney would be fit to face Boro.
“I hope so. I would like. He is always a player I would like to have, but I have my little doubts. Let’s see the evolution.”
United travel to the London Stadium on January 2 for their first game of 2017 and Rooney will be hoping to be part of the squad.
Should he fail to recover in time, however, the forward will hope to feature in United’s FA Cup third round clash against Reading at Old Trafford, ahead of their upcoming EFL Cup semi-final first leg encounter with Hull City.
United then play arch-rivals Liverpool at home on January 15.
