After easily defeating the Bears, the Seahawks remained at home to face the winless Detroit Lions. This game was controversial due to a missed call that drastically altered the Lions' chances of winning. The Seahawks led 13-3 heading into the 4th quarter. Wilson was sacked and fumbled, and the Lions defense ran it back for a touchdown, cutting the deficit to 13-10. After the Seahawks' offense had a 3 and out, the Lions had the ball at their 10-yard line. They reached the red zone a few minutes later. On 3rd and 1, Stafford completed a pass to Calvin Johnson, who reached the Seahawks' 1 yard line and attempted to reach out and score the go ahead touchdown. As Johnson was brought down, Kam Chancellor stripped the ball from him. K.J. Wright then knocked the ball out of the back of the end zone. The referees ruled it a touchback, giving the Seahawks the ball back on their 20-yard line. The Seahawks ran two plays, forcing the Lions to burn their timeouts. On 3rd and 2, Wilson completed a pass to Kearse, gaining the first down.  With no timeouts remaining, the Seahawks kneeled, ran out the clock, and ended the game, winning 13-10. As a result, the Lions dropped to 0-4. Wright's bat play caused controversy afterwards. Minutes after the game ended, the NFL VP of officiating ruled that Wright illegally batted the ball out of the back of endzone. Had the call been made, a penalty would have been assessed that gave the Lions a 1st down at the spot of the fumble, plus half the distance to the goal (6-inch line). The officiating crew was heavily criticized by analysts, fans, and players following the missed call.  Several comparisons were immediately made to the Seahawks' controversial victory over the Green Bay Packers in Week 3 of the 2012 season, which also happened on Monday Night Football. In the postgame press conference, Carroll admitted that Wright intentionally batted the ball out of the back of the endzone, and Wright confirmed it. Chancellor said that he did not see the controversial play.
