Bath and England flanker Sam Underhill is expected to miss the rest of the season after suffering a serious toe injury.
Underhill, who came on as a replacement and was sin-binned in England's Six Nations loss to Scotland last month, ruptured a tendon during a training session with the national squad when a team-mate trod on his foot.
"He could be out anything from eight to 10 weeks," Bath director of rugby Todd Blackadder told BBC Radio Bristol.
"He's essentially ruled out for the rest of the season."
The 21-year-old made his England debut against Argentina last year and has gone on to win six caps.
