Kellen Winslow will not be suspended under the NFL's substance-abuse policy after being found in possession of synthetic marijuana.

Synthetic marijuana is not on the NFL's list of banned substances.

"Our drug policy is one that has strict and well-defined drugs that are banned," union boss DeMaurice Smith said, via NJ.com. "If they are not on the list, they can't serve as the basis for discipline." 

The owner of the St. Louis Rams has purchased a 60-acre parking lot located between the Forum and Hollywood Park in Los Angeles.

Wal-Mart originally owned the land, but sold it after failing to receive public approval for a store. Stan Kroenke, owner of the Rams, is a former board member of Wal-Mart and husband of one of Bud Walton's daughters.

Los Angeles has been without an NFL franchise since after the 1994 season.

This marks the first time an NFL owner has purchased land in Los Angeles capable of accommodating a stadium.

Los Angeles already has two other competing NFL stadium proposals, with one next to Staples Center and the other in the City of Industry.

Jahvid Best is suing the NFL, helmet maker Riddell and Easton-Bell Sports over concussion.

Best was a first round pick in 2010 and is now out of football after suffering a series of concussions.

The civil lawsuit can only seek monetary damages and at this point, Best's attorney, Bret Schnitzer, said he did not have a specific monetary damage being sought.

"The purpose behind the lawsuit, there's a number of requests of release in the lawsuit," Schnitzer said. "One of them is to set up a medical fund for Mr. Best in order to deal with future medical conditions out of this concussion syndrome.

"As I am sure you are probably aware through various media and the 'Frontline' program and so on, the brain injuries with concussion syndrome does not necessarily manifest itself completely immediately, as you can see from the other cases. Sometimes it is 10, 20 years where the brain injury process takes to develop and it's not necessarily going to show itself in a 24-, 25-year-old football player to the extent that it might 10, 15, 20 years down the road.

"So one of the goals of the litigation is to protect Mr. Best down the road in terms of his medical condition and problems that he may have in the future."

The Detroit Lions are not listed in the suit.
