Detroit Lions 41 at Tennessee Titans 44 on September 23rd, 2012 - Full team and player stats and box score
www.pro-football-reference.com
The Lions scored with 18 seconds left got the onside and hit a hail mary to tie it
The Chiefs 4th down started with 15 seconds left after a time out, it Houston blocks the punt for a TD, it is feasible for them to get the onside kick with 5-7 seconds left, throw a hail mary and win, or even with one time out, maybe get into field goal range to tie. Unlikely sure, but not impossible
You take the safety which happens with 11 seconds remaining after the punter wastes a little time running around, kick it away and Houston likely gets the ball around the 30-35 yd line needing 2 scores, That is impossible
