It was exactly a month ago when Kristoffer Ajer went off injured in Celtic’s 1-0 Cup victory over St Johnstone.

The Celtic manager was pessimistic at the time and believed the Norweigan would be out for the better part of six weeks.

However, Ajer has surprised many by popping up at Lennoxtown training on Friday apparently ahead of schedule.

The Celtic defender was a first choice pick before going out injured with him and Boyata the centre-back pairing.

Celtic have struggled to keep consistency in their backline so far this season with injuries to key players at key times and even a combination of suspension and injuries this weekend has thrown Celtic’s semi-final plans off.

Ajer back in training is a welcome boost but the Hearts tie comes too early for the youngster.

If he is to get game time in the next week it could well be against the Jambos at Celtic Park the following Saturday.
