Jones sustained a calf injury in Week 16 that caused him to miss practice this week. Though he returned as a limited participant in the Chiefs’ drills on Tuesday, Kansas City officially listed him as questionable for its tilt against the Steelers. It is unclear how much time—if any—Jones will need to miss due to his current condition.

The Kansas City Chiefs will be without two important players for their Christmas Day matchup against the Pittsburgh Steelers. Kansas City ruled out left tackle D.J. Humphries in its final injury report, while defensive tackle Chris Jones, officially listed as questionable with a calf injury, is also inactive.
