Emmanuel Sanders, Derek Wolfe injured in Broncos practice

ENGLEWOOD, Colo. -- Denver Broncos wide receiver Emmanuel Sanders left Thursday’s practice with a hamstring injury while defensive end Derek Wolfe left the workout after taking a blow to the helmet.

Sanders, who limped slightly as he left the field, was being evaluated after practice and Wolfe will be evaluated under the guidelines of the concussion protocol.

“[Sanders] was having a great day … just trying to get a ball and he felt something,’’ said Broncos coach Gary Kubiak. “Obviously going to be smart there.’’

Linebacker Steven Johnson also left practice after taking a hit on the knee and cornerback Curtis Marsh was pulled out of practice late when he felt some tightness in his thigh.

Kubiak said he didn’t believe, at least initially, Sanders’ injury was too severe, but the Broncos won’t be in a hurry to rush him back to the practice field with over a month to go before the start of the regular season. Wolfe will now have to be cleared by the Broncos' medical staff as well as an independent physician to return to practice.

The Broncos were missing linebacker Danny Trevathan (illness) on defense, but Trevathan is expected to practice on Friday. Linebacker Lerentee McCray (groin), safety Ross Madison (groin), cornerback Tevrin Brandon (shoulder), nose tackle Marvin Austin Jr. (groin) and tackle Michael Schofield (back) were held out of practice.
