SAN FRANCISCO (KRON) — San Francisco District Attorney Brooke Jenkins announced Thursday that she had entered into a “friendly wager” on the Super Bowl with her counterpart in Kansas City. Under the terms of the bet, each prosecutor has agreed to wear the opposing team’s jersey in a social media post if their hometown team loses Sunday.

In Kansas City, Jackson County District Attorney Jean Peters Baker has agreed to wear a Brock Purdy San Francisco 49ers jersey if the Kansas City Chiefs lose. Back in the City by the Bay, DA Jenkins has agreed to wear a Patrick Mahoney Chiefs jersey if the Niners lose.

The first Super Bowl in Las Vegas has everything the imaginary NFL scriptwriters could’ve wanted.

There’s Patrick Mahomes and the underdog Kansas City Chiefs (14-6) aiming to become the first repeat champions in 19 years and trying to solidify their claim to a dynasty with a third Super Bowl title in five years.

There’s Brock Purdy returning from a significant injury after rising from “Mr. Irrelevant” to now lead the San Francisco 49ers (14-5) to the brink of a record-tying sixth Super Bowl title that would etch his name alongside Pro Football Hall of Famers Joe Montana and Steve Young.

Of course, there’s the glitz and glamour of America’s showcase city and the irony of playing a Super Bowl in this gambling capital, an idea that used to be taboo for the NFL.

Did we mention Taylor Swift yet?

Make room for the Grammy-winning superstar to jet into town just in time to see her boyfriend, Travis Kelce, try to win another ring. Swift is expected to fly in for Sunday’s game at Allegiant Stadium from Japan after her concert on Saturday.

Kelce, the four-time All-Pro tight end, is focused on limiting the distractions despite fielding numerous questions this week about Swift and their relationship that has captivated millions and attracted a new audience of football fans.

“Show up every day thinking about the now and not too much the future,” Kelce said. “Obviously, you gotta prepare for what’s ahead but not harp on the past is the biggest thing … I think we would never try and tie in what we did last year to this year. Every single year is really its own journey.”

For the Chiefs, nothing less than hoisting another Vince Lombardi trophy is acceptable so they have the most pressure.

For the 49ers, there is unfinished business to attend to.

Super Bowl LVIII is a rematch of Super Bowl LIV four years ago when the Niners fell to the Chiefs 20-31, and some of the current 49er stars such as tight end George Kittle, receiver Deebo Samuel and linebacker Fred Warner.
