Chargers coach Brandon Staley revealed Friday that quarterback Justin Herbert suffered a fractured rib cage during Thursday night’s 27-24 loss to the Chiefs.

The announcement came hours after NFL Network’s Ian Rapoport reported that Herbert was scheduled to undergo a “battery” of tests to determine the severity of the rib/chest injury he suffered late in the game. Staley told reporters that the team has listed the star QB as day-to-day, but is encouraged by the early diagnosis.

“I think we got good news,” Staley said, per NFL Network’s Taylor Bisciotti. “It’s going to come down to comfort. We won’t know more about how he feels until later in the week. “

Staley also noted that Herbert is likely to return to practice next week. The Chargers host the Jaguars on September 25.

Herbert battled through noticeable pain after taking a hit to his midsection on a tackle by Chiefs defensive end Mike Danna with just over five minutes to go in regulation. After retreating to the sideline for just one play, the 24-year-old quarterback returned to the field and finished the game. He finished the night 33-of-48 for 334 yards, three touchdowns and an interception.
