The 30-year-old, who has 61 international caps to his name, has previously captained the side under former manager Craig Levein and is now expected to wear the armband under Gordon Strachan in the friendly match at the National Stadium in Warsaw.
Having won his battle with ulcerative colitis, the bowel condition that had kept him sidelined for around two years, Fletcher made his return to United’s first team in December and has since made nine appearances for David Moyes’ men.
During a recent interview with Inside United, the Scot explained why he's keen to make up for lost time. "I always feel that if you put caps on just being happy and settling for stuff, then you can never progress yourself," he said.
"So I see that I've got a lot of lost time to make up for. I want to try to put those two years on at the end of my career."
