DENVER (AP) — Broncos receiver Wes Welker is being evaluated for a possible concussion after taking a hit to the head from Houston defensive back D.J. Swearinger in a preseason game Saturday night.

Welker was leveled by Swearinger soon after catching a short pass over the middle late in the second quarter. Swearinger drew an unnecessary roughness penalty for the hit on Welker, who has a history of concussions and wears a bigger helmet to further protect his head.

Broncos quarterback Peyton Manning gave Swearinger an earful after throwing a 29-yard TD pass to Emmanuel Sanders. Manning ran down the field and muttered something to Swearinger, which earned the QB a taunting penalty.

Welker missed the final 3½ games last season after sustaining his second concussion in a three-week span.
