Coming off back-to-back home wins to start the season, the Broncos traveled to CenturyLink Field for an interconference duel against the Seattle Seahawks, hoping to avenge their 43-8 blowout loss to the Seahawks in Super Bowl XLVIII. On the Broncos' first possession, Seahawks' safety Kam Chancellor forced a fumble off running back Montee Ball deep in Broncos' territory. The ensuing Seahawks' drive culminated in placekicker Steven Hauschka settling for a 20-yard field goal. The Broncos drove down the field on their next possession, but had to settle for a 24-yard field goal by placekicker Brandon McManus. Both teams traded punts on their next two possessions, until the Seahawks re-claimed the lead late in the second quarter, with a 39-yard touchdown pass from quarterback Russell Wilson to wide receiver Ricardo Lockette, then added to their lead with a 5-yard touchdown pass from Wilson to running back Marshawn Lynch just before halftime. After a scoreless third quarter, which included Broncos' defensive tackle Terrance Knighton blocking a 46-yard field goal attempt by Hauschka, Britton Colquitt sent a punt that backed up the Seahawks to their own 8-yard line to begin the fourth quarter. Three plays later, Lynch was tackled in the end zone by linebacker Nate Irving and cornerback Aqib Talib for a Broncos' safety to narrow the Seahawks' lead to 17-5. The Broncos were forced to punt on their first possession of the fourth quarter, and on the Seahawks' next possession, Wilson was intercepted by cornerback Chris Harris, Jr., who advanced the football to the Seahawks' 19-yard line. Five plays later, the Broncos' offense finally got into the end zone, with quarterback Peyton Manning connecting on a 3-yard touchdown pass to tight end Julius Thomas. The Seahawks were forced to punt on their next possession, and the Broncos' offense got the football with 6:07 remaining in the fourth quarter. On the ninth play of the drive, the Broncos were facing a 3rd-and-11 at the Seahawks' 24-yard line, however, a Manning pass intended for wide receiver Wes Welker was intercepted by Chancellor, who advance all the way to the Broncos' 35-yard line. Five plays later, Hauschka made a 28-yard field goal to increase the Seahawks' lead to 20-12, with 1:04 remaining in the fourth quarter. With no timeouts remaining, Manning engineered an 80-yard drive in only 35 seconds, which included two key pass completions &#8212; a 42-yarder to wide receiver Emmanuel Sanders and a 12-yarder to wide receiver Demaryius Thomas. On the sixth play of the drive, Manning completed a 26-yard touchdown pass to tight end Jacob Tamme, coupled with a two-point conversion pass from Manning to wide receiver Demaryius Thomas to send the game into overtime, tied at 20-20. However, the Seahawks won the overtime coin toss, and methodically marched down the field with a 13-play, 80-yard drive, culminating in a game-winning 6-yard touchdown run by Lynch to end the game.
