Berra set to miss Gretna clash

Berra: One booking away from ban

Frail's decision will be influenced by the defender being only one booking away from picking up a two-game suspension for the start of next season.

Winger Saulius Mikoliunas is back in Lithuania for the birth of his child, while Robbie Neilson (pelvis), Christian Nade (concussion), Calum Elliot (back) and Andrew Driver (thigh) are all expected to remain sidelined.

Frail could give the club's youngsters a chance to impress as a disappointing campaign draws to a close at Fir Park in what could prove to be financially-stricken Gretna's last-ever match.

Hearts (from): Banks, Ridgers, Thomson, Zaliukas, Goncalves, Karipidis, Kingston, Jonsson, Wallace, Stewart, Screpis, McGowan, Cesnauskis, Palazuelos, Glen, Mole, Rapnik, Ivaskevicius.
