Javorius Allen scored two touchdowns, Joe Flacco passed for 277 yards and a score, and the Baltimore Ravens beat the Denver Broncos 27-14 in Baltimore on Sunday.

Alex Collins rushed for 68 yards and a touchdown for the Ravens (2-1).

Case Keenum threw for 192 yards and an interception. He also fumbled in Denver's poorest offensive showing of the young season. The Broncos scored on their first two possessions but finished the game with seven straight punts, an interception and a failed fourth-down conversion.

Emmanuel Sanders and Royce Freeman scored touchdowns for the Broncos (2-1), who lost two players during the game. Cornerback Tramaine Brock suffered a groin injury in the first half, and running back Phillip Lindsay was ejected for throwing punches in a pileup for a loose ball after Keenum fumbled.

Safety Darian Stewart was also hurt but returned.

The Broncos started fast after linebacker Joseph Jones broke through the line and blocked Sam Koch's punt to set up a first-and-goal at the 6 for Denver. Freeman ran it in untouched on the next play to give the Broncos a 7-0 lead.

Baltimore responded on its next possession. A 37-yard kick return and a 15-yard penalty on Denver set up the Ravens at the Broncos' 48. Five plays later Collins scored on a 6-yard touchdown run to tie it at 7-7.

Denver came right back to take the lead on an eight-play, 70-yard drive. Sanders capped it with a 35-yard reverse for his first career rushing touchdown that made it 14-7.

Denver's offense stalled after that, allowing Baltimore to take over. A 52-yard field goal by Justin Tucker cut the deficit to 14-10 late in the first. Flacco later led the Ravens on a 52-yard drive capped by Allen's 12-yard touchdown reception.

The Broncos appeared to take the lead on a blocked field goal that Chris Harris Jr. scooped up and returned for a touchdown. But a penalty on the return and a penalty on the drive forced a punt. Tucker kicked another 52-yard field goal at the end of the first half to lead 20-14.

Allen scored his second touchdown on a 1-yard plunge up the middle to give the Ravens a 13-point lead midway through the third quarter. Denver had two drives end in the red zone in the fourth quarter, but Keenum was intercepted and the Broncos then failed on fourth down.
