Chiefs start reporting for camp with roster 90% vaccinated KANSAS CITY, Mo. (AP) — Patrick Mahomes and several of his Kansas City Chiefs teammates reported for training camp Friday, with 90% of the team’s roster having received the COVID-19 vaccine. “There’s six teams that are over 90%, so we’re glad to be in that area there,” coach Andy Reid said. “We’re one of the teams where the players have really challenged themselves to get things done and take care of business.” The Chiefs are holding training camp on the campus of Missouri Western State University in St. Joseph, and Reid says fans will notice new procedures when attending practices this summer. Players will not be signing autographs and other measures are being taken to increase health safety for players and other club employees. Reid reported that 100% of his staff has received a vaccine.
