Travis Kelce
The Kansas City Chiefs suffered a tough start to their title defense in 2023. Their star tight end Kelce suffered a freak knee injury in a practice that prevented him from playing. Reportedly, he hyperextended his knee and it took him out of their season-ending game against the Lions.

In the end, it was a major blow because the Chiefs narrowly lost this game. Detroit stole it after Kansas City made several key mistakes. Some people also said that it was a sign that Patrick Mahomes couldn’t win on his own. The brilliant quarterback struggled to find his weapons without Kelce as an option (via USA Today Sport).
