49ers still remember Super Bowl defeat to Chiefs.

Sin City — When asked about his most memorable Super Bowl experience, San Francisco 49ers defensive tackle Arik Armstead wasted no time getting the story out.

Third-and-15 to Tyreek Hill, down the field," Armstead announced. "It changed the game."

For a couple of reasons, several 49ers have been reliving the Super Bowl LIV losing memories during the last week.

To begin with, they have returned to the Super Bowl. Furthermore, the opponent is none other than the Kansas City Chiefs, who defeated them exactly four years ago.

In the final quarter, the 49ers had a 20-10 lead. The advantage and the possibility of a title were swiftly erased, beginning with the third-and-15 play that Armstead vividly recalls. 

Hill escaped for an additional 44 yards. A return was initiated. "Jet Chip Wasp" was the play-call that became legendary in Kansas City. The Chiefs eventually prevailed, 31-20.

Nine 49ers players from the game are still active. A loss like that is impossible to forget.

"The pain you feel when you lose a Super Bowl is unmatched," stated 49ers fullback Kyle Juszczyk on Monday, Super Bowl Opening Night.
