Sean Smith has received a three-game suspension from the NFL for a violation of their substance abuse policy.

Smith produced a strong season in 2014, finishing as the fifth-best cornerback in the league, according to Pro Football Focus. Starting all 16 games for the Chiefs last season, the 27-year-old cover man allowed just 57 percent of passes thrown his way to be completed.

Smith pled guilty in April on a 2014 DUI charge.
