After scraping through in the FA Cup, Manchester United turn their attention to an important run of Premier League games in the final three weeks of February.
After recently returning to training, Amorim confirmed Shaw had suffered a small setback in his recovery when speaking before the Leicester game.
“Luke has one small issue in the different area from the last injury, so we try to be careful with Luke,” he said.
There have been reports that Shaw faces another four weeks out but conflicting reports say he could return to training this week.
Friday’s fortunate 2-1 win over Leicester, secured by an injury-time winner by Harry Maguire which looked offside, showed United remain a work in progress.
