The Kansas City Chiefs' nightmare of a season just got even scarier. Franchise superstar quarterback Patrick Mahomes suffered a big hit to his head in the fourth quarter of the Chiefs' game against the Tennessee Titans. Jim Wyatt of TenneseeTitans.com reported that backup Chad Henne entered the game after Mahomes got hit.

The injury occurred in the midst of a blowout loss to the Titans, who went on to win the game 27-3. The Chiefs are now 3-4 on the season, marking the first time Kansas City has had a losing record in Mahomes' professional career. They are now tied for the worst record in the AFC West with the Denver Broncos.

Kansas City has been thoroughly disappointing to this point in the season, though the majority of the blame should not fall on Mahomes or the offense. Their defense has been a catastrophically bad unit so far, surrendering points at will.

Admittedly, Mahomes has been shaky at times this season, throwing way more interceptions than he usually does. But through six games, he has also posted the highest completion percentage of his career so far while leading the league in passing touchdowns (18) entering today's game.

Kansas City's attempt to redeem their loss in Super Bowl LV now looks as shaky as ever. Should they continue failing miserably on defense, their playoff hopes look to be shot. Those hopes will look much, much worse if Mahomes misses significant time.
