It all started when Dahl, a free-agent signee who played for the Rams from 2009 to 2012, said the Rams were able to beat and tie the 49ers in their two games last season partly because the 49ers were tipping their plays. That led to a response from the Rams cornerback, who called Dahl "lame and weak."
Cue Long, via Twitter:

In truth, by the time the teams square off in Week 4, it will have been 634 days since the Rams lost to the 49ers. That calculates to one year, eight months, 25 days (or for you alternative time counters: 90 weeks; 15,216 hours; 912,960 minutes; 54,777,600 seconds).
The rubberest of rubber matches will be played Thursday, Sept. 26, on NFL Network (call your local cable or satellite provider for channel info).
