SAN DIEGO, Sept. 14 (UPI) -- Jake Plummer and Clinton Portis had a big first half before going down with injuries Sunday as Denver coasted to a 37-13 rout of San Diego.
Ranked next-to-last in the NFL after struggling in his Broncos' debut, Plummer took advantage of an inexperienced secondary and completed 9-of-13 passes for 94 yards and three touchdowns. But he landed on his head while diving for a first down midway through the second quarter and suffered a concussion.
Portis rushed for 129 yards on 12 carries. His success allowed Plummer to throw play-action TD passes to fullback Reuben Droughns and tight end Shannon Sharpe, but he took a blow to the chest before halftime and did not return.
Plummer and Portis helped Denver (2-0) build a 24-10 lead before turning things over to Steve Beuerlein and Mike Anderson.
Anderson added 65 yards and a touchdown on 16 carries.
