Havenstein has already missed four games this season with an ankle injury and now could be out for a crucial divisional game against the Cardinals. It's worth noting that Havenstein rarely participates in the team's final practice of the week.
The 10-year veteran was part of the Rams' 2022 Super Bowl-winning team and has spent his entire career with the organization.
Havenstein currently holds a 74.1 overall PFF grade, which is 28th out of 135 offensive tackles this year. His 66.9 pass-blocking grade ranks 63rd while his 78.3 run-blocking grade places 13th.
Havenstein has five penalties on the season and allowed three sacks and 20 pressures in 683 offensive snaps.
If Havenstein isn't able to go, backup Joe Noteboom will get the start. Noteboom has given up two sacks and nine pressures in 97 offensive snaps this season (27 at left tackle, 70 at right tackle).
The Rams (9-6) can clinch the NFC West title with a win over the Cardinals (7-8) this week and a win over the Seattle Seahawks in Week 18.
