Friday, coach Andy Reid officially declared the quarterback out Sunday versus the Green Bay Packers.
Mahomes was limited in practice after suffering a dislocated kneecap in K.C.'s Week 7 win over the Denver Broncos. He practiced on a limited basis all week. Until Friday, Reid wouldn't rule out the signal-caller despite most believing there was little chance he'd suit up. Today, reality settled in.
"He just wasn't ready," Reid said of Mahomes. "He needs a little bit of time here."
NFL Network Insider Ian Rapoport reported after Mahomes' injury that the QB was likely to miss three games at least. The Chiefs might hope to beat that timetable after Mahomes was able to get in limited practices this week.
With Mahomes out, veteran Matt Moore will get the start. In relief last week, Moore completed 10-of-19 passes for 117 yards, one touchdown, no interceptions and an 89.1 passer rating. For his career, the 35-year-old owns a 15-15 record as a starter with a 60.4 completion percentage, 192.4 passing yards per game, 41 TDs, 26 INTs and an 85.3 rating.
