Bath centre Andrew Higgins could be sidelined for two months after suffering an ankle injury.
Higgins was hurt during Bath's opening pre-season tour game against Berea Rovers in South Africa last week.
"It is too early to tell what the damage is yet, and Andrew will be seeing a specialist for a further opinion," said Bath head coach John Connolly.
Bath, who are in friendly action against the Neath-Swansea Ospreys tonight, launch their Zurich Premiership campaign at Northampton tomorrow week.
