The Facts: The Rams placed Mason on the reserve/did not report list Saturday.

Diehards Line: Mason was a no-show when the full squad was required to report on Friday for the team’s first camp at the University of California-Irvine. The team had excused Mason from the offseason program due to personal reasons. Last week, TMZ reported that police were called to Mason’s house for the fifth time in four months. It’s probably not a surprise to team officials that Mason didn’t show up for camp, but it still has to be concerning given his recent arrests and the additional police visits. Mason, who turns 23 next week, has been the Rams’ backup running back for the last two seasons. He got limited work last season with the emergence of Todd Gurley, but he’s scored five touchdowns and averaged 3.8 yards per carry on 254 carries over two seasons.
