The Kansas City Chiefs put on a brilliant performance against the Pittsburgh Steelers on Sunday. They've dominated in all three phases as Kansas City becomes the first team in the AFC to clinch a spot in the postseason. However, it might have come at a cost, as Tyrann Mathieu went down with an injury.

According to James Palmer, Tyrann Mathieu was ruled out with a quad injury. His absence didn't affect the Chiefs against the Steelers. However, there is a chance the injury lingers. If that's the case, Mathieu's injury could prove to be crucial for Kansas City's playoff run.

For now, everything is speculation, as there is no official update on Mathieu's quad. The Chiefs will be monitoring their star safety closely throughout the week, as he plays an important role for this team. Kansas City's defense has come alive in the back half of the regular season, proving they have what it takes to take another stab at another Super Bowl.

We'll see how it plays out, as Mathieu will have some time to rest his quad. Hopefully, it's not a serious injury and he can return to the lineup in Week 17. Considering the Chiefs have clinched a spot in the postseason, it might be wise for the coaching staff to ease Tyrann Mathieu back into the lineup.

Keep an eye on Tyrann Mathieu and the Chiefs, as they'll provide updates on Mathieu's status. Kansas City must take care of their players, as Clyde Edwards-Helaire fell to a collarbone injury against the Steelers as well. This is the worst time of the season for a team to gather injuries. However, everything is up in the air as the franchise will monitor their star players.
