In a thrilling Christmas Day matchup, rookie Xavier Worthy put the Kansas City Chiefs ahead early with a touchdown catch from Patrick Mahomes. However, his celebration led to an unsportsmanlike conduct penalty, and kicker Harrison Butker missed the extra point, leaving the score at 6-0.

Worthy has been a standout performer for the Chiefs, leading the team with nine touchdowns this season. The Pittsburgh Steelers, meanwhile, have struggled defensively, allowing their 12th first-quarter touchdown of the season, the highest in the league.
