Rochdale manager Keith Hill will be reluctant to make any changes.
Dale have won their last four matches without conceding a goal and climbed to the brink of the play-off places in the process.
Tuesday's 2-0 home win over Charlton underlined Dale's pedigree, and Hill has a full-strength squad to choose from for his 200th Football League game in management.
Hill feels all the pressure will be on Gus Poyet's side, saying: "It's the easiest game of the season for us because nobody is expecting us to win.
"Brighton aren't top of the division for nothing, they are an excellent side brimming with excellent players.
"They were always my favourites to get promoted and Gus has done a fantastic job."
Adam El-Abd and Ashley Barnes are back in contention for Brighton.
Defender El-Abd has missed the last two games with a hamstring injury but is back in the squad and will vie with Tommy Elphick for his place at centre-half.
Striker Barnes has been sidelined for three matches with an ankle injury but has resumed training this week and will be handed a late fitness test.
Full-back Jim McNulty is still out after ankle surgery and midfielder Jamie Smith remains on the sidelines with a foot injury.
The Seagulls head into April 13 points clear at the top having won all eight of their matches in March to set a post-war club record.
