The Chiefs will have to make their playoff push without their starting center in the lineup. On Friday, the team announced that Morse is headed to injured reserve with a foot injury. Cornerback Keith Reaser has been promoted from the practice squad to take his place on the roster. 
Without Morse, the Chiefs will be forced to put fourth-year pro Zach Fulton in the starting lineup. Swingman Cameron Erving will serve as Fulton’s primary backup.
Morse, 25, first suffered the injury in the Chiefs’ Week 2 game against the Eagles. He returned in late October, but the issue flared up again in the Chiefs’ recent loss to the Jets. Morse was carted off the field in that game and had to be held out of Sunday’s win over the Raiders.
The loss of Morse comes at a particularly bad time as the offensive line has to contend with the Chargers’ tenacious pass rush.
“They’re playing very well right now,” Chiefs coach Andy Reid said this week (via the Chargers’ website). “Their pass rush is tremendous right now. It was good against us. Look at our third downs the last time we played them; they got after us. They’re playing at a very high level, and the secondary, they don’t do a lot but they do it very well. They have a great defensive coordinator. Gus does a great job there. They’re in good hands.”
The Chiefs have a 64% chance of winning the division, according to the playoff odds calculated by the New York Times. Of course, those odds decrease significantly if they lose on Saturday.
