Head coach Sean McVay said that Havenstein (ankle) will be sidelined for the Rams' Week 10 game next Monday versus the Dolphins, Sarah Barshop of ESPN.com reports.
The Wisconsin product sustained an ankle injury in the Rams' Week 9 win over the Seahawks, and McVay's decision to already rule Havenstein out for Week 10 suggests the issue could be serious. Joe Noteboom (ankle) could step in as a replacement for Havenstein at right tackle in Week 10 if he's activated from injured reserve.
