FAYETTEVILLE Former Arkansas offensive lineman DeMarcus Love received a four-game suspension for violating the NFL's performance-enhancing substances policy.

The NFL announced the suspension Thursday.

Love is preparing for his third season with the Minnesota Vikings after being a sixth-round draft pick in 2011. His agent, Thomas Simms, told CBSSports.com that Love took an over-the-counter sleep aid that contained the banned substance.

Simms told CBSSports.com Love "deeply regrets this incident" and "looks forward to esuming his playing career for the Vikings organization and contributing to the 2013 football season."

Love has not played in a regular season game in his NFL career. He was inactive for every game in 2011 and missed 2012 with a pectoral injury.

The Texas native played at Arkansas from 2006-10 and started every game as a junior and senior.

Love can participate in practices and play in preseason games before his four-game suspension begins.
