Task: Question Understanding
Input (English): Passage: For the second time in a three-week span, the Broncos faced their AFC West rivals, the San Diego Chargers. Following a 28-yard field goal by placekicker Brandon McManus on the Broncos' opening possession, a 7-yard touchdown pass from quarterback Philip Rivers to tight end Antonio Gates gave the Chargers their only lead of the game. The Broncos' defense then proceeded to frustrate the Chargers' offense, including three interceptions of Rivers. In the second quarter, Broncos' cornerback Bradley Roby returned an interception 49 yards for a touchdown, and Chargers' placekicker Josh Lambo later missed on a 44-yard field goal attempt. On the Chargers' opening possession of the second half, the Broncos took advantage of a Rivers' interception deep in Chargers' territory, and added to their lead, with running back Devontae Booker rushing for a 3-yard touchdown. Rivers subsequently threw another interception deep in Chargers' territory, his third of the game; however, a fumble by Booker gave the football back to the Chargers. Thirteen plays and 98 yards later, the Chargers narrowed the Broncos' lead, with a 14-yard touchdown pass from Rivers to wide receiver Travis Benjamin. Broncos' linebacker Shaquil Barrett blocked the extra point attempt, keeping the score at 17-13. The Broncos responded early in the fourth quarter, with running back Juwan Thompson rushing for a 1-yard touchdown. On the Broncos' next possession, quarterback Trevor Siemian was intercepted by Chargers' cornerback Casey Hayward, who returned the football 16 yards for a touchdown. The initial two-point conversion pass from Rivers to Gates was successful, however, it was nullified by an offensive pass interference penalty on Gates. Rivers' second attempt intended for tight end Hunter Henry was incomplete, keeping the score at 24-19 with 8:10 remaining in the game. Two long pass plays from Siemian&#8212;one to tight end Virgil Green for 31 yards and another to wide receiver Demaryius Thomas for 40 yards&#8212;gave the Broncos a first-and-goal at the 4-yard line. However, the Chargers' defense forced the Broncos to settle for a 22-yard field goal by McManus. The Chargers attempted a rally, and with 2:54 remaining, the Chargers had a first-and-goal at the 2-yard line, but Rivers threw four consecutive incompletions, the last of which was knocked away by Broncos' cornerback Lorenzo Doss at the goal line. While backed up deep in their own territory, the Broncos' offense went three-and-out, and were forced to punt, giving the Chargers one last possession. The Broncos' defense stood their ground, not allowing the Chargers to advance past midfield. Broncos' defensive coordinator Wade Phillips was rushed to a Denver-area hospital, following a second-quarter sideline collision after Chargers' running back Melvin Gordon was blocked into him. Linebackers coach Reggie Herring filled in for Phillips for the remainder of the game.
