The San Francisco 49ers are officially rumored to be looking at firing Jim Tomsula, with any news expected no later than Monday. Jason Cole said he confirmed Pro Football Talk's report, but also said nothing was final. Ian Rapoport said he is hearing no decision has been made on Tomsula's future. Whatever the case, it appears tenuous at best right now.
The Monday immediately after Week 17 is referred to as Black Monday. It is the day coach firings generally become official. Teams generally will not wait any longer to fire a coach, and plenty have already gotten in on the action.
