CHICAGO — The idea that NFL players might use Viagra to gain an edge on the field left Chicago Bears linebacker Lance Briggs practically in tears — from laughing.

He wasn’t the only one.

Players cracked jokes about it Thursday, a day after Bears star receiver Brandon Marshall said he had heard that some players were using Viagra and hoping it would give them an advantage during games. Punch lines aside, experts say it’s unlikely the erectile-dysfunction drug would help.

“What would that do? That’s the most ridiculous thing I’ve ever heard,” Minnesota Vikings long snapper Cullen Loeffler said.

Bears defensive back D.J. Moore wondered if Marshall was kidding and said: “I’ve never heard of that.”

NFL spokesman Greg Aiello said Viagra is not a banned substance and declined further comment.

Marshall started it all Wednesday when asked about a growing number of suspensions tied to amphetamines, including the ADHD drug Adderall. He said he didn’t know much about Adderall, but suggested Viagra could be viewed by players as a way to boost their energy.

“I know guys, it’s such a competitive league, and guys try anything just to get that edge,” he said. “I’ve heard of guys using Viagra, seriously, because the blood, it’s supposed to thin… I don’t know. Some crazy stuff. It’s kind of scary with some of these chemicals that are in some of these things, so you have to be careful.”

Arizona Cardinals defensive lineman Vonnie Holliday, a 15-year NFL veteran, said some of his teammates were talking about Marshall’s Viagra remarks but he had never heard of such a thing himself.

“I don’t understand what good it would do,” he said.
