The joint, however, has improved considerably in the last 24 hours and now interim boss Gordon Chisholm is hoping his absence from normal duties will be measured in days, rather than weeks.

“The whole thing is a bit of a mystery because Derek did not feel anything during the game and can’t remember taking a knock.

“It was even a good while after the match before his knee swelled up,” said Gordon.

“It does feel a lot better today, though, and I am still hopeful he will be in the squad against Livingston on Saturday.”

Long-term injuries apart, McInnes was the only player not to take part in today’s first-team squad session.

That spelled good news for goalkeeper Tony Bullock and defender Mark Wilson, both of whom had been taking things easy since the start of the week because of knocks.

Their participation this morning was confirmation they will be in their usual places come Saturday.

Meanwhile, Gordon Chisholm’s No. 2 Tony Docherty has joined an increasing number tipping teenage sensation Garry Kenneth for a big future.

The 17-year-old has been a rock at the heart of the rearguard since being drafted into the team because of injury last month and his performances have not surprised Tony, who worked extensively with the Dundonian at youth team level.

“Garry can go all the way, it’s really going to be up to how much he wants it. He was identified as someone special at a very young age and came through all our Dundee training schools to first-team level,” said Tony.

“He has developed physically and mentally over the last year and you have to keep reminding yourself that he’s only 17.

“He has played against Bellamy, Hartson, Prso, Novo, Riordan, O’Connor and Lee Miller and none of them have had it easy.

“He has a great attitude and is always willing to learn so, if he stays like that, he’ll go right to the top.”
