Nottingham Forest striker Taiwo Awoniyi is "progressing well" in his recovery from injury.

The Reds striker suffered a groin problem in the draw with Brentford and missed the game at Crystal Palace just before the international break. He is expected to be sidelined for about a month but could soon be back in training.

Forest could also be without full-back Gonzalo Montiel for Saturday's clash with Luton Town. The Argentine was forced off when playing for his country against Peru this week.

Serge Aurier is a doubt to face the Hatters, too. He made way at half-time of the 0-0 draw at Selhurst Park.

"He's only just got back in the country," head coach Steve Cooper said of Montiel. "We'll assess it ourselves. We've seen the initial scans and it does look like a calf injury.

"Serge walked off at Crystal Palace. He picked up an injury there.

"The players who were injured before that game continue to be that way. They are not in training at the moment.

"You want everyone fit, but that's often not the case. We'll get ready for the game with the players we have available.

"Gonzalo has only just come back, so we'll have to get the medics to assess it properly so we can see the extent of it. Hopefully it's not as bad as what it might be. It looks like a muscle injury, but we'll wait and see.

"Taiwo is progressing well. He's not far off some training, so let's see how the next week goes, going into the game after Saturday."

Ola Aina (muscle), Nuno Tavares (groin), Danilo (hamstring) and Felipe (knee) have been out of action for the Reds. Cooper's men host Luton at the City Ground aiming to get back to winning ways after four matches without a victory.
