Celtic's Gary Hooper and Emilio Izaguirre are vying with Rangers' Steven Naismith and Alexei Eremenko of Kilmarnock for the PFA Scotland's Player of the Year award.
Striker Hooper and left-back Izaguirre have been crucial components of Neil Lennon's side, with Celtic top of the SPL table with seven matches remaining this season.
Rangers midfielder Naismith will be hoping to beat Hooper and Izaguirre to the award and the SPL title, having helped Walter Smith's men to Co-operative Insurance Cup success against Celtic last month.
Kilmarnock playmaker Eremenko, who is on loan from Ukraine's Metalist Kharkiv, is the fourth nominee, having helped the Ayrshire side secure a top-six place this term.
Hooper is also among the nominees for PFA Scotland's Young Player of the Year.
The 23-year-old is joined in the shortlist by Dundee United's David Goodwillie, Aberdeen's Chris Maguire and Hearts winger David Templeton.
The winners will be announced at a dinner in Glasgow on Sunday 1st May.
