Chiefs quarterback Patrick Mahomes has been ruled out for Sunday's game against the Packers, coach Andy Reid announced on Friday.
The decision comes a little over a week after Mahomes dislocated his kneecap in a Thursday night game against the Broncos on Oct. 17. Mahomes returned to practice this week, but backup Matt Moore took the majority of the team's reps.
Reid told reporters that Mahomes "just wasn't ready" for Sunday's matchup.
Moore replaced Mahomes in the second quarter of Kansas City's game against Denver and finished the 30–6 win with 10 of 19 passes completed for 117 yards, including a 57-yard touchdown to Tyreek Hill.
An MRI later showed that Mahomes suffered a dislocated knee and the Chiefs' hope was that the reigning MVP could return in three weeks, if not sooner.
Sunday will mark Moore's first start since Week 11 of the 2017 season with the Dolphins.
The Chiefs will also be without defensive tackle Chris Jones, defensive end Frank Clark, cornerback Kendall Fuller, left tackle Eric Fischer and offensive guard Andrew Wylie.
The Chiefs and Packers will face off on Sunday night at 8:20 p.m. ET.
