Rangers duo Alfredo Morelos and Ryan Kent are up against Celtic pair James Forrest and Callum McGregor for PFA Scotland's Player of the Year.
Morelos is the top scorer in the Scottish Premiership this season with 17 goals in 27 games and has also registered four assists.
The 22-year-old Colombia striker is joined alongside Rangers team-mate Kent, on loan from Liverpool, in a four-man shortlist with Celtic's Scotland international duo Forrest and McGregor.
Forrest and McGregor have been standout performers for league leaders Celtic this season, who are chasing an unprecedented treble-treble and need just a point from their last three games to be sure of the Scottish Premiership title.
McGregor said: "To be nominated by your fellow professionals shows you are doing something right and people are taking notice of it. It is nice to be in the running."
Forrest added: "It is a good boost. It shows that you have been consistent all season and it is good to be involved in."
Morelos and Kent helped Steven Gerrard's side qualify for the Europa League group stage this season, ending their eight-year absence from Europe, while the Ibrox club also reclaimed second place in the league from Aberdeen.
Rangers winger Kent has six goals and six assists in 23 top-flight games this season, while in 30 games for Celtic, Forrest has 11 goals and 12 assists and McGregor has three goals and 10 assists.
Kent is also nominated for PFA Scotland's Young Player of the Year, joining Aberdeen's Lewis Ferguson, Motherwell's David Turnbull and Jake Hastie - who signed for Rangers from Motherwell on Wednesday.
Speaking of his nominations, Kent said: "It's a great feeling. It's been quite a tough season, a long season but to be nominated for these awards is an achievement in itself so I'm happy.
"I was optimistic coming up here. I was hoping to get good things out of this season and on a personal level it's been a good year."
