The striker bagged an early contender for Goal of the Season as he launched Forest’s fight back from 2-0 against Birmingham on Saturday.
Cox started the game on the bench after picking up a foot injury a few days earlier while on international duty for the Republic of Ireland.
But he made a lasting impression by taking his goal tally to three in six appearances since joining The Reds from West Brom and will be hoping for a starting role at Palace.
First team coach Jimmy Floyd Hasselbaink told us: “Simon is a great player. He has settled in really well with us and you can see that he’s enjoying his football.
“He’s a proper footballer – he likes to do things the right way. He’s bright in training and you can see in games that he’s playing with a smile on his face because he’s really enjoying himself.”
Hasselbaink scored more than 250 goals in a glittering career with the likes of Leeds, Chelsea, Middlesbrough and Atlético Madrid.
But he told Forest Player: “I never scored a goal like Simon’s – mine were all tap-ins.
“It was a great goal. He showed great technique and that’s something you’ve either got or you haven’t.”
Forest have no fresh injury concerns ahead of the trip to Palace and Marcus Tudgay is likely to be available again after recovering from a groin problem.
Reds fans are reminded that tickets for the Palace game will be available tonight at Selhurst Park. They can be purchased from the visiting supporters’ box office in Park Road.
