Isaiah Pead suspended one game for violating substance-abuse policy
Going into this season, it appears that it would be a relatively open competition for touches between Pead, Richardson and rookie Zac Stacy.
That said, Pead won't be in the mix when the Rams host the Cardinals in Week 1 of the 2013 season.
Per Ian Rapaport of NFL Network, Pead has been suspended for one game for violating the league's substance-abuse policy.
Pead had only 10 carries last season for a total of 54 rushing yards in addition to three receptions for 16 yards.
Although Pead can practice with the team and participate in preseason games, a strong performance by either Stacy or Richardson in Week 1 could potentially reduce touches in future weeks.
