Aberdeen midfielder Callum Roberts is facing up to ten weeks on the sidelines after suffering a hamstring injury last weekend.
The news was confirmed by Dons’ boss Jim Goodwin on Thursday as the club prepare to host Motherwell in league action on Saturday.
Roberts only signed for the Pittodrie club from Notts County last month and made his debut as a sub against Celtic in the opening day of the season.
The 25-year-old then came off the bench again in the 4-1 Premiership win over St Mirren last Saturday but had to be taken back off again after picking up the injury.
Goodwin was happy to confirm Hayden Coulson’s knock was not as bad as feared but had more gloomy news about Roberts, saying: “The scans for Hayden Coulson’s injury was better than first feared initially.
“This weekend is going to come too soon for him unfortunately but he will be back in the squad at the early part of next week and Callum Roberts unfortunately, his one is worse than we thought initially.
“And it looks as if Callum is going to be out for quite a significant period of time, it is looking at probably eight to ten weeks I would imagine.”
