Bath have confirmed that back-row pair Taulupe Faletau and David Denton face time on the sidelines after injuries last weekend.
Faletau, signed from Newport Gwent Dragons this season, is out for up to eight weeks after suffering knee ligament damage against Northampton.
"He's had a scan this week. It's anything from six to eight (weeks)," Bath boss Todd Blackadder said.
Denton meanwhile tore his hamstring against Northampton and will miss four months, ruling him out of the November internationals for Scotland.
Bath are interested in bringing back former number eight Leroy Houston on loan from the Queensland Reds to cover for both injuries.
Speaking after his side's outstanding 58-5 win over Newcastle Falcons, Blackadder with Bath's performance.
"I'm just so pleased for our players. It was fantastic," he said.
"It was a great atmosphere. The support here is unbelievable. You just feel the passion and commitment to the team. The support we got today was amazing. Long may it continue."
