While the Kansas City Chiefs said they had a prepared strategy in the event that the Super Bowl went to overtime, multiple San Francisco 49ers players admitted they were not even aware of the rules.

"I didn't even know about the new playoff overtime rule, so it was a surprise to me," defensive lineman Arik Armstead said. "I didn't even really know what was going on in terms of that."

Sunday night's game was the second of 58 Super Bowls to be tied after regulation. It was the first played under new overtime rules that ensure both teams get a chance to possess the ball before the game ends -- unless the first drive in OT ends with a safety.

This differs from the rules governing overtime in the regular season, where the game ends if the first team to possess the ball scores a touchdown.

After winning the overtime coin toss Sunday, the 49ers elected to receive the ball to start the extra period. But their 13-play drive ended with Jake Moody's 27-yard field goal and set the stage for Mahomes, who orchestrated his own 13-play drive punctuated by a game-winning 3-yard touchdown pass to Mecole Hardman that sealed the Chiefs' 25-22 victory.

"You know what? I didn't even realize the playoff rules were different in overtime," Niners fullback Kyle Juszczyk said. "I assume you just want the ball to score a touchdown and win.

"I guess that's not the case. I don't totally know the strategy there. We hadn't talked about it, no."
