In a big game, both the Chargers and Chiefs had plenty riding on a victory. After a frigid matchup, plenty of notes and takeaways can be immediately discussed.

The Kansas City Chiefs just suffered a heartbreaking loss to the Los Angeles Chargers on Sunday, 16-13. Patrick Mahomes had to exit the game late in the fourth quarter due to an injury, which required backup quarterback Gardner Minshew to step in. Minshew, however, was picked off in what turned out to be the final play of the game.

NBC News and the Washington Post, citing officials briefed on the investigation, reported the person of interest as Benjamin Erickson. USA TODAY has not independently verified that report. Erickson, 24, has not been charged and has not been named as a suspect in the shooting.
