Marshall practices at start of Broncos quarterback camp

The Denver Broncos’ quarterback camp opened Monday with Brandon Marshall running routes but catching no passes and Travis Henry out the first week with a pulled hamstring.

The Broncos feared that Marshall would miss the start of training camp in July after cutting an artery, a vein, a nerve, two tendons and three muscles in his right arm in an accident in March at a resort in Orlando, Fla.

“June 22 will be his first day he’s able to catch the football, which gives us plenty of time before we start our summer ball,” coach Mike Shanahan said.

Henry is expected back next Tuesday after pulling a hamstring during 100-yard drills Friday.

Marshall is key with Javon Walker out at wide receiver. Denver brought in some experience, signing Keary Colbert, Sami Parker and Darrell Jackson to play opposite Marshall.

“Anytime you lose a guy like Javon Walker like we did, you want to bring in some people you feel that can compete right away, some guys that have some experience,” Shanahan said. “You never have enough depth at that position. Hopefully we have more depth this year than we’ve had.”
