Per Adam Schefter:
Cowboys' LB Rolando McClain will be suspended the first 10 games for violating the NFL’s substance abuse policy, per @toddarcher and me.

There are already rumors of the Dallas Cowboys potentially parting ways with McClain due to the suspension. McClain has played for the Cowboys the past two years and has totaled 161 tackles during that time.
