Charlton boss Karl Robinson hopes to know more about Stephy Mavididi’s injury in the next 24 hours.

The Arsenal loanee was substituted with a hamstring problem in the 3-2 defeat to Oxford United last weekend.

Mavididi, 19, has damaged the same hamstring which sidelined him for several months last year, however, this fresh injury is not thought to be as serious.

Robinson told News Shopper: “We’re still not 100 per cent clear yet. We’re hoping to get more clarification from Arsenal in the next 24 hours. It’s a little worse than we thought. But we’ll have to wait and see what it is.

“We think it’s part of the muscular tendon in the hamstring. It is on the same leg but it’s a completely different injury.

“We have to clarify everything with Arsenal before we decide on timescales. He saw a specialist on Monday night. We’ve got a plan for him, but there are so many different theories behind it, so it would be difficult to give a definite [return] date for him.

“He’s unlucky, injuries are just part and parcel of the industry, unfortunately.

“All of his injuries have come when he’s been off balance. We’re devastated for him, but it’s certainly not as bad as the last injury.”

Meanwhile, Nicky Ajose is set to return to first-team training tomorrow.

The striker, who was recalled from his loan at Bury last month, has been struggling with a groin complaint.

Robinson added: “Nicky will start training on Thursday so we’ll introduce him very slowly. The players have worked really hard in the last two days.

“He was going to play in an Under-23s game on Monday, he wanted to play in it and we stopped him [as a precaution].

“If he’s fit, he’ll be involved [in the matchday squad at Doncaster].”
