The Seahawks travelled to Denver to face their old foe from the AFC West. On a frigid Sunday Night game, these Seahawks were able to accomplish what few of their predecessors managed - to come out of Denver with a win. Carrying on their recent troubling tendency of weak first half performances, the Seahawks fell behind 13-7 to the Broncos, who were led by first-time starter Jay Cutler. The Seahawks managed only 2 first downs and 67 yards of total offense in the first half, but remained in the game thanks to Darryl Tapp's 25-yard return of an intercepted Cutler pass for a TD. In the second half, the teams traded punts and one turnover apiece until Seattle got the ball on its own 39-yard line with 9:42 left in the game. Two long pass completions from Matt Hasselbeck to Darrell Jackson put the Seahawks on the Broncos one-yard line. Shaun Alexander quickly took the ball into the endzone for a 14-13 Seahawks lead. The Broncos fumbled the ensuing kickoff, and Joe Tafoya recovered. Assisted by a holding penalty on third down, the Seahawks moved the ball into range for Josh Brown to kick a 44-yard field goal. The Broncos held onto the following kickoff, but on their first play Cutler threw an interception to Jordan Babineaux for Seattle's  9th takeaway in the past two games. The Seahawks again had to settle for a Brown 23-yard field goal for a 20-13 lead with 3:01 remaining, keeping Denver in the game. The failure to score a TD proved costly, as Cutler connected with WR Brandon Marshall on a 71-yard pass and run play for a game tying TD, assisted by some poor tackling by Seattle. The Seahawks started the last drive at their own 14-yard line with 2:31 remaining. A key third down reception by Nate Burleson kept the drive alive, and Hasselbeck led the team down to the Broncos 32-yard line with 10 seconds remaining. Josh Brown came on to kick a game-winning, 50-yard FG, his fourth such kick of the season to tie an NFL record. With the win the Seahawks' lead in the NFC West increased to three games over the 49ers and Rams as they improved to 8-4.. How many defensive touchdowns were scored in the first half?
