Carrick has been struggling with a niggling problem for some time, but cam through 90 minutes in Sunday’s 1-0 victory over Arsenal at Old Trafford.
Carrick said: “I have been carrying the injury for a few weeks now. I was a bit patched up to play today.
“I got through it but it doesn’t look too good.”
The 32-year-old playmaker has been a key player for United in recent years and has appeared in 15 of their last 18 matches so far this season.
