Seagulls boss Graham Potter is expecting Schelotto, who has been out for six months with the injury suffered on loan at Italian side Chievo, to be back in his plans for the game at the Amex Stadium on Saturday.
However, midfielder Yves Bissouma, yet to feature this season because of a shoulder issue, is expected to return to training next week.
Winger Leandro Trossard is set to be out of action until after the next international break due to a groin injury he sustained while on international duty with Belgium.
The news is a timely blow for Potter given that forwards Florin Andone and Jurgen Locadia both recently departed Brighton on loan, joining Galatasaray and Hoffenheim respectively, and winger Jose Izquierdo still sidelined by a knee problem.
However, apart from Nigerian defender Leon Balogun needing an extra day to recover from slight tightness, Potter revealed that "everyone else has come back fit and ready from their national sides".
The dearth of forwards could see 19-year-old striker Adam Connolly feature again after he came off the bench to make his top-flight bow in the defeat at Manchester city last time out.
Potter said: "We've got plenty of players who we think can help us in the attacking positions.
"It's about working with what we have and helping them to keep getting better."
Brighton, who won their opening match of the season 3-0 at Watford, face a Burnley side that also have four points from their first four games this term.
The Clarets are without on-loan Chelsea man Danny Drinkwater, who is ruled out for several weeks with an ankle injury suffered during an alleged drunken dispute with another football outside of a nightclub.
Elsewhere, the injury situation is looking healthy for boss Sean Dyche with McNeil recovered from the slight back and hamstring injuries that forced him to miss a possible England Under-21 debut.
Forward, Barnes is also over a minor groin problem, while Johann Berg Gudmundsson will be further assessed to see whether he's ready to return yet from a calf injury which forced him to miss the defeat to Liverpool and Iceland's Euro 2020 qualifiers.
Robbie Brady wasn't available for Ireland but featured for the Clarets' Under-23s and the winger is expected to be back in the squad.
