Coventry City full-back Marcus Hall has suffered another injury blow.

The 23-year-old defender, who came up through the youth ranks, has damaged a knee in pre-season training and is unable to do fitness work with the rest of the squad.

It is the latest blow for the England B international who has been hampered by groin and knee problems in the past.

Hall has, despite making over 70 first team appearances, failed to nail down a senior spot and faces a vital year in his career.

Manager Gordon Strachan will discover in the next few days whether Coventry born Hall will be fit enough to go on the club’s four-game tour of Germany next week.

Strachan said:

"He may well have been doing too much running on hard surfaces during the summer in a bid to be ready. He will look at him in the next few days and see how he is.

"He is another who faces a very big season. He has got to start forcing his way in. He is a man and he has got to start giving a man’s performance."

City could also be without Belgian Laurent Delorge when they fly out at the weekend. The youngster, who broke a leg in his first game for the club after moving from Ghent, is still suffering from a hamstring strain.

Strachan added:

"We have had four days of training so far and it has gone very well. We have worked on toning the lads up ready for this week when we will go up a level or two.

"The lads have come back in good condition and they have to realise that if they want to move up a level and be internationals then their summer breaks will get shorter."
