Maguire is set to undergo a scan to ascertain the seriousness of the problem but, at the moment, he is not expected to be out for an extended period of time.
The centre-back has only recently returned from another injury, having been sidelined for the FA Cup tie versus Nottingham Forest, and the league fixtures against Manchester City, before making his comeback in the 4-3 win over Liverpool.
It remains to be seen whether this latest setback is a recurrence of an old issue.
