SWANSEA welcome back Kyle Naughton and Martin Olsson for their Premier League relegation battle with Middlesbrough on Sunday.

Right-back Naughton has missed the last two games with a hamstring problem, while left-back Olsson sat out the 2-0 defeat at Bournemouth before the international break due to an ankle injury.

Ki Sung-yueng, Jefferson Montero and Kristoffer Nordfeldt were the last three Swansea players to return from international duty and all are likely to be on the bench.

Provisional Swansea squad: Fabianski, Naughton, Fernandez, Mawson, Olsson, Cork, Carroll, Fer, Routledge, Sigurdsson, Llorente, Nordfeldt, Kingsley, Amat, Van der Hoorn, Britton, Fulton, Ki, Montero, Ayew, Narsingh, Borja, McBurnie.
