TEAM NEWS
Amorim should provide an update during his press conference on Monday, but some clues may be gleaned from access to United's training session at Carrington this Friday.
Ayden Heaven was substituted in pain during the second half of our last outing, at Leicester, and it remains to be seen how long the in-form defender will be sidelined for.
Mason Mount returned to the matchday squad as an unused substitute and Harry Maguire and Leny Yoro were not thought to be far away from a comeback.
The Reds are still likely to be missing a host of first-team names though, including Amad, Lisandro Martinez and Kobbie Mainoo, all of whom have been sidelined since February.
Forest's primary concern is top scorer Chris Wood, after he was forced off with a hip injury during New Zealand's World Cup qualifier against New Caledonia. The problem is thought not to be as bad as first feared, although the 33-year-old will be assessed on his return to Nottingham.
He has been ruled out of the Emirates FA Cup quarter-final at Brighton & Hove Albion this weekend.
