​On Wednesday, November 4, Los Angeles Rams head coach Sean McVay announced that veteran defensive back Jaylen Watson — once a key member of the Kansas City Chiefs’ secondary — will have season-ending shoulder surgery.Watson entered the league as a seventh-round pick of the Chiefs in the 2022 NFL Draft and was a valuable contributor in Kansas City’s victories in Super Bowls LVII and LVIII. The former Washington State Cougar signed a three-year, $51,000,000 contract with the Rams as a free agent earlier this year and served as a veteran presence in Los Angeles’ defensive backfield for the team’s first seven games of the 2026 NFL regular season. #Rams CB Jaylen Watson is expected to have shoulder surgery that will end his 2026 season, coach Sean McVay said.
