Wolves attacker Pedro Neto is battling to make today's Black Country derby against West Brom.
The 20-year-old winger struggled towards the end of the 2-1 loss to Everton on Tuesday night after being fouled by Abdoulaye Doucoure.
He managed to carry on but was in obvious discomfort following the 'big knock'.
On whether Neto will be fit for the much-anticipated clash with Albion at Molineux (12.30pm), Nuno said: "He's inside all the players we have to assess, realising we still have a lot in front of us.
"At the same time, Pedro is doing well, so we'll decide tomorrow.
"He had a big knock but is improving. Better today, and hopefully better tomorrow."
