Danny Welbeck will miss out on a reunion with former club Arsenal after sustaining a hamstring injury in Brighton & Hove Albion's shock win against Manchester City.
The English forward lasted less than half an hour before limping off against the champions and will play no part at the Emirates Stadium on Sunday.
Brighton boss Graham Potter therefore has a choice to make up top, where Andi Zeqiri - a substitute against City - could be handed his first Premier League start.
Leandro Trossard scored from the bench in midweek and appears certain to come into the side here, likely alongside Alexis Mac Allister in a 3-4-2-1 formation.
Albion are boosted by the return of Lewis Dunk at the back as the defender has completed a two-match ban, freeing up Dan Burn to move across to left wing-back.
On the other flank, Pascal Gross is likely to get the nod - no player has more Premier League assists in 2021 than the German (six).
Neal Maupay is still banned, however, and the visitors also remain without injured pair Solly March and Tariq Lamptey, while Davy Propper and Joel Veltman are fitness doubts.
Brighton possible starting lineup: Sanchez; White, Dunk, Webster; Gross, Bissouma, Lallana, Burn; Mac Allister, Trossard; Zeqiri
