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.

Players cracked jokes Thursday, a day after Bears receiver Brandon Marshall said he heard some players were using Viagra, hoping it would give them an advantage on the field. Punchlines 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.
