Josh McEachran will miss the rest of the season after the ankle injury he sustained at Sheffield Wednesday.
The Brentford midfielder was showing his best form in the 18 months he'd been at the club before the blow that ended his season.
And head coach Dean Smith revealed that he is set to return for another scan to double check that the former Chelsea man hasn't suffered any further damage.
He said: “Josh has not trained with us yet. The rehabilitation has taken longer than expected.
“I think he's going to have another scan to make sure we've not missed something. I would have thought that's his season over. I can't see him being fit for Blackburn next week.”
Maxime Colin hobbled off against QPR and is rated as 50/50 for Saturday's game with Fulham.
Smith added: “Maxime Colin was struggling before the game but he declared himself fit. He had a strain in his calf muscle. He came off with 30 minutes to go so he'll be touch and go for Saturday.”
Aside from long term absentees Alan Judge and Lewis Macleod the Bees have been dealt a clean bill of health for their regular starters.
Smith confirmed: “Woodsy got a whack on the foot which he had an x ray on. It's okay but swollen. Andreas should be back in the squad but he's not played minutes since Ipswich so it'd be a risk to play him.
“Alan McCormack – this game might come too quickly for him. That's about it. Woodsy and Lasse have had their stitches out so they're all fighting fit.”
