The midfielder has not been able to take part in full training since, though is on course to take part in Saturday’s session in a bid to prove his fitness before Forest welcome the reigning Premier League champions to the City Ground.
“Morgan Gibbs-White is doubtful. He couldn’t train the entire week with us, but it looks like he can join tomorrow’s session, and he had an individual session today with our rehab coaches,” Glasner revealed in Friday’s press conference.
“He suffered a minor muscle injury at Palace, so we have to see how he reacts today and how he deals with tomorrow’s session. Then I will take the final decision.
“In a long season, this is a situation that happens, especially when players are going away and playing for their countries for more than two weeks.
“It’s not to blame anybody; it’s just that every manager has a different style of training, which the body has to get used to, with a different load.
“It doesn’t seem too serious, so there is a chance he will be available.”

In addition to Gibbs-White, Nikola Milenkovic is a doubt after returning to training following over a month on the sidelines with a hamstring issue.
However, Nicolo Savona and Igor Jesus remain unavailable for selection against Arsenal because of injuries.
