Reyna came off the bench in the second half and, at the time, Forest were down 1-0 at home against opponents Crystal Palace.
The game's opening goal came 11 minutes in, with Jean-Philippe Mateta providing the finish. The striker's finish was a relatively simple one, as Eberechi Eze squared the ball to Mateta to help Palace seize the lead.
With Forest trailing, Reyna was thrown on in the 60th minute, and, less than a minute later, the hosts were level. It came via a lovely header from Chris Wood, who rose to meet a Morgan Gibbs-White cross to tie the score at one apiece.
Reyna went on to have a solid chance a few minutes later, only to be thwarted by Dean Henderson as the match finished level.
