Lasse Vibe is set to return to the Brentford squad for their trip to Ipswich Town on Saturday.
The Dane has been out of the side with a calf injury that has caused him to miss the wins against Sheffield Wednesday and Rotherham United.
However, he has returned to light training so is in contention for a place in the matchday squad.
Philipp Hofmann is another one in contention for a return after missing recent games with a back injury but the trip to Portman Road is likely to be too soon for him.
Smith added: “Philipp Hofmann is training with us. He's still a bit sore and running a bit gingerly around the place.
“He's had a nasty back injury. We'll have to wait and see whether it's too early for him.”
Josh McEachran has been ruled out of the side after his ankle injury against Sheffield Wednesday.
Smith revealed: “Saturday will come too early for Josh. He had a whack on the ankle and hopefully we'll have him back soon.”
Alan McCormack is another absentee after yet another injury interrupted his season with the club taking a cautious approach with him.
Smith explained: “Alan McCormack is still not on the training ground yet. We've had to take a softly softly approach as he's broken down so many times.”
Alan Judge is set to step up his return from a horrific broken leg next week when he returns to part-contact training.
Smith said: “Judgey is in non contact training with us. He's still non contact. We're hoping that will change next week and go to part contact.
“He's still not full contact yet. We can put him into coaching sessions where there isn't likely to be a full blooded challenge on him but keep him out of small sided games where he might get a full blooded challenge.
“I think, from what I believe the outlook to be from the start, was that it could be over a year given the injury it was.
“We have to make sure it's healing properly. Before we move onto the next step, we have to tick boxes.
“He's out on the training ground and scoring goals. I think he wants to tackle himself. We have to keep the reins on him slightly.”
