UNDATED (AP) — A person familiar with the situation tells The Associated Press that Kansas City Chiefs quarterback Patrick Mahomes escaped significant damage to ligaments when he dislocated his right kneecap against Denver and could be back in 4-6 weeks. The person spoke on condition of anonymity Friday because the Chiefs have not revealed any sort of timetable for his return. Mahomes underwent an MRI exam earlier in the day.

The reigning league MVP was hurt during the Chiefs’ 30-6 win in Denver on Thursday night while sneaking for a first down on fourth-and-short deep in Broncos territory. Everyone jumped up from the pile but Mahomes, who immediately grabbed for his right knee as trainers rushed onto the field.

Team physicians were able to get his patella back in place on the field. The Chiefs play Green Bay a week from Sunday, then face the Vikings and Titans before a Monday night matchup against Tennessee on Nov. 18. The Chiefs (5-2) have their bye the following week, so it is possible they hold Mahomes out until Dec. 1 against Oakland. The Packers-Chiefs game was supposed to be a Sunday night showdown between Mahomes and Green Bay counterpart Aaron Rodgers. Now it’s merely an intriguing matchup of playoff contenders.

Chiefs coach Andy Reid said journeyman quarterback Matt Moore, who was signed just before the season, would be the starter going forward, and that rookie Kyle Shurmur — the son of longtime NFL coach Pat Shurmur — could be elevated from the practice squad as the backup.
