The on-loan defender has been sidelined for the past three months, and having come near to a return, has suffered another setback.
Another who will miss Saturday's trip to Leeds is midfielder Alan McCormack , but he should be back in training next week.
Bees boss Dean Smith said: “The squad's looking well, there's a lot more bodies on the grass now, and it's good to see Alan Judge out there sprinting. He's just starting to get his deceleration sorted in terms of his mechanics, which is good.
“Alan McCormack's part training with us on Monday, which is a big boost with the festive period coming up. Alan picked up a groin injury in the Newcastle game and as injured all the time he was suspended. He had a course of injections into his groin area and is nearly fit again.
“Rico Henry's been out doing a bit of non-contact work but Callum Elder has gone back to Leicester for a little bit of treatment. He had a knock back with his hamstring, so we sent him back for Leicester to have a look.”
He added: “These three week games are tough and take a lot out of the players, but we've had two really good performances and two really good results. Just getting those results has given everyone a rise in confidence, and suddenly you're looking up rather than over your shoulders.
“Tuesday could have gone either way in terms of the chances created by both teams, but we got over the line at the end, and I was really pleased with the last 15 minutes and how we saw the game out.
“What we've had are poor results, but with the exception of Norwich, they've not been poor peformances. The last two results haven't surprised me, but we're in a world where results are scrutinised.”
