Brighton will be without Gary Dicker when they host Nottingham Forest.
The Irish midfielder suffered a knee injury in training after colliding with goalkeeper Casper Ankergren.
Boss Gus Poyet revealed Dicker has not suffered any ligament damage, but he will not be ready in time for the weekend.
Poyet can welcome back Lewis Dunk into his squad after the defender served a one-match ban in the 2-2 draw with Charlton last Saturday.
Right-back Bruno had to come off at The Valley with an Achilles problem but he will be in the squad.
Fellow Spaniards Andrea Orlandi (broken rib) and Vicente (thigh) are still missing although the latter is stepping up his training as he bids to be available for the first time since August.
Simon Cox could be in line for a shock Forest return when they make the trip.
Cox, who was originally expected to be sidelined for a minimum of two months with ankle ligament damage, could make his comeback just three weeks later at the Amex Stadium.
The former West Brom striker is likely to settle for a place on the bench, though, with Dexter Blackstock and Billy Sharp set to continue in attack.
Defender Daniel Ayala was only named among the substitutes for last weekend's win over Burnley after failing to shake off a bout of illness and could now return to the starting line-up.
Fellow defender Greg Halford (calf) and midfielder Jermaine Jenas (calf) are both expected to miss out again.
