Midfielder Moussi pulled a thigh muscle in the build-up to Forest`s second goal in their 2-1 win at Coventry on Tuesday night and will undergo a scan on Thursday to assess the seriousness of the injury.
New signing Findley, who is yet to feature for the Reds, has also sustained a thigh injury in training and needs a scan to determine how long he faces on the sidelines.
Tyson, meanwhile, missed out at the Ricoh Arena with a back injury and will be assessed.
