The Lions striker's assist in the Play-Off Final has been named the best of the 2016/17 season.
Gregory's headed flick across goal was buried by strike partner Steve Morison in the dying stages of the tie at the national stadium.
The goal proved the difference as The Lions secured promotion to the Sky Bet Championship over rivals Bradford City.
Gregory's assist received 30 percent of fans' votes in our poll to narrowly take the prize ahead of Shaun Williams' precise long pass against Charlton Athletic, which attracted 28 percent of the votes, and Steve Morison's deft cross against Scunthorpe (18 percent).
