Bo Nix's broken ankle has placed Jarrett Stidham into most unusual territory.
After throwing no passes and taking four offensive snaps all season, Stidham will now take over as starting quarterback for the Denver Broncos in the AFC title game against New England on Sunday.
Stidham hasn't thrown a pass in a regular season or playoff game since starting the final two contests in 2023, getting his only action in practice and the preseason since then.
According to Sportradar, Stidham will be the seventh quarterback since starts began being tracked in 1950 to start a playoff game in a season when he didn't start in the regular season.
Frank Reich was the only one of those six QBs to win as a fill-in when he won two starts for Buffalo in the 1992 playoffs in place of Jim Kelly.
Stidham will join Joe Webb as the only QB to start a playoff game after not throwing a pass in the regular season and the second to make his first start in the conference title game or Super Bowl. Roger Staubach made his first start in the 1972 season in the NFC title game for Dallas the year after winning Super Bowl MVP.
Here's a look at the six QBs who started a playoff game in a season when they had no regular season starts:
