Here are other injuries we're monitoring Monday:
- Kansas City Chiefs wide receiver Sammy Watkins suffered a tight hamstring in the first quarter of Monday's game against the Denver Broncos, coach Andy Reid said after the game. He left the game and was declared out for the remainder of the contest by the team. ESPN's Lisa Salters reported Watkins ran on the sideline before the start of halftime, but he indicated to team trainers he wasn't feeling good enough to return.
During the second half, veteran linebacker Dee Ford left the game with a groin injury, Reid said.
- Jacksonville Jaguars coach Doug Marrone said running back Leonard Fournette will be sidelined again because of a lingering hamstring injury. Fournette had 11 carries in the Jaguars' win over the New York Jets but was unable to finish the game. He missed the Jaguars' previous two games after first suffering the injury in Week 1.
"It's probably going back to when he first hurt it," Marrone said. "I don't know how long it will be. We'll take it day-by-day. ... There's a thing that is pulling at it."
