The Kansas City Chiefs are managing various player injuries as they begin their NFL season. Initial concerns centered on left tackle Josh Simmons, whose back injury left his status for the Week 1 game against the Denver Broncos uncertain.

By the third week of the season, Simmons remained listed as week-to-week. While head coach Andy Reid noted that Simmons is “working his tail off” and showing progress with decreased swelling, the team has not set a return timeline and has kept him off injured reserve. Additionally, rookie cornerback Mansoor Delane was available for a game against the Indianapolis Colts following a shoulder injury, though he was limited to emergency situations and did not see game action.
