Celtic have had a week off, after their match against Hamilton was postponed at the weekend.
Commons and Forrest have been carrying knocks, but a week off has served them well.
Celtic’s match against Hamilton was postponed at the weekend, and Collins feels that both Forrest and Commons have benefitted from the break – as they will now be able to feature against Fenerbahce on Thursday evening.
“Thankfully, James and Kris were available for the game and were in the squad, though whether they were ready to start the game I’m not quite sure,” said Collins. “The good news is they had an extra few days to train hard and get ready for Thursday.
“Those with short-term knocks – James and Kris – are coming along nicely and ready with the group to go again. “
Whether Forrest or Commons will be risked on Thursday night by Ronny Deila remains to be seen, as there is little pressure on the match.
Celtic are simply playing for pride against Fenerbahce, as their exit from the Europa League has already been confirmed.
Collins was also unable to bring any further good news about Celtic’s injured players.
The assistant manager was unable to provide a progress update on Charlie Mulgrew, Scott Brown and Saidy Janko, who are all set for a lengthy spell on the sidelines.
“Charlie will still be out and Browny and Saidy will be longer-term as well,” he added.
