On October 29, the Chiefs hosted the defending NFC champion and former division rival,  the Seattle Seahawks.  The game marked the first time the Seahawks had played at Arrowhead since joining the NFC.  The game was broadcast on Fox at noon Kansas City time. Trent Green had been cleared by doctors to practice again with the team, but he required a minimum of 2 more games to adjust to playing time.  Backup quarterback Damon Huard was injured in the days before the game and was expected to miss the game, but he was declared fit to start.  On the Chiefs radio coverage during the game, play-by-play announcer Mitch Holthus called the game "The Backup Bowl." Offensive tackle John Welbourn practiced with the team, but it was not known if he will be welcomed back to the team following a suspension violating the league's steroid policy.  He later came back after Week 8 after serving his suspension.  The Chiefs also signed offensive tackle Chris Terry to a two-year contract.  Previously, Terry had been suspended from the NFL for four games in 2003 for violation of the policies on substance abuse and personal conduct. In the second quarter, the Chiefs' Lawrence Tynes connected on a 32-yard field goal adding to the Chiefs' lead 13-7.  Quarterback Seneca Wallace responded to the Chiefs' lead by throwing to Wide receiver Deion Branch, who went out of bounds in front of the end zone.  The Chiefs challenged the call as they believed Branch did not have possession while in bounds.  Replays showed Branch caught the ball while in the air and while one foot landed in bounds, the other stepped on the line.  The review booth was experiencing technical difficulties. so the referees declared the call stands. The Chiefs' defense held the Seahawks for the remaining time in the fourth quarter after Jared Allen intercepted a tipped pass from Seneca Wallace.  Allen had the ball stripped by Deion Branch near the Seattle 27-yard line.  Seattle challenged Allen's possession as it was later seen that Branch recovered the ball before going out of bounds.  The referees took nearly four minutes in reviewing the play, where new NFL rules claim that referees should take no longer than 90&#160;seconds or else the play will stand.  The call was reversed and Seattle regained possession with less than two minutes remaining and one timeout left. In the last few moments in the game, Derrick Johnson managed to get the Chiefs' first sack on Seneca Wallace and the Chiefs' defense held the Seahawks to secure the win.  With the win, the Chiefs climbed above .500 for the first time in the season.. How many points were the Seahawks trailing by after Lawrence Tynes kicked a 32-yard field goal in the second quarter?
