Alexandre Frutos is poised for his first Albion start at Sheffield Wednesday on Monday.
Frutos is in line to make his full debut for the Seagulls, as Richard Carpenter has been ruled out by injury.
Albion received the results of a scan yesterday on the recurring foot problem which has troubled Carpenter for a month.
He is expected to see a specialist tomorrow but physio Malcolm Stuart has already confirmed Carpenter is a non-starter for the trip to Hillsborough.
The central midfielder was forced off midway through the first half of Tuesday's morale-boosting 1-0 win away to arch rivals Crystal Palace.
Carpenter had already been in the wars at Selhurst Park before that. His head had to be bandaged and he needed four stitches in a gash above the left eye, sustained in an aerial duel with Palace's Tom Soares.
Frutos made his seventh successive substitute appearance on the left flank following Carpenter's early departure, with Dean Hammond switching back into the middle of the park.
The former Metz wide man put in another sound shift and manager Mark McGhee is likely to keep things the same for the journey to South Yorkshire.
Albert Jarrett, who had been keeping Frutos out of the side on the left wing, was dropped from the squad against Palace.
Jarrett's replacement, Charlie Oatway, had one of his best games in an Albion shirt and the captain seems sure to retain his place at the heart of the action alongside Hammond.
Fifth-bottom Albion and fellow strugglers Sheffield Wednesday will both be keeping an eye on the fortunes of those at the bottom of the Championship tomorrow.
Basement side Millwall entertain Southampton, next-to-bottom Crewe go to Cardiff and Coventry, adrift of Albion on goal difference, are at Leicester.
Monday's hosts are a point and two places worse off with a game in hand ahead of the Sky televised clash.
Meanwhile, support is growing for ex-Albion and Celtic boss Liam Brady to be the Republic of Ireland's next manager.
Ladbrokes have slashed Brady's odds from 33-1 to 7-1 joint third favourite to succeed Brian Kerr, behind Martin O'Neill and David O'Leary, after a plunge by punters in Dublin and Glasgow.
