EL SEGUNDO, Calif -- Los Angeles Chargers quarterback Justin Herbert said Wednesday he suffered a sprained left ankle in the team's 19-17 loss to the Kansas City Chiefs on Sunday.

Herbert sat out practice Wednesday because of the ankle injury, as well as a thigh contusion also suffered against the Chiefs. He said he wasn't sure of the severity of the sprain.

Herbert previously suffered a high right ankle sprain in Week 2 against the Carolina Panthers, forcing him to wear a walking boot. He didn't miss any games but was significantly hobbled until after the Chargers' Week 5 bye.

"I would say that this one is probably not as severe," he said. "It's definitely painful enough to be able to miss a practice, but I feel like I've been able to move around a little bit better this week than I did after Carolina, where I was put into a boot and had difficulty walking."

The ankle injury happened on the Chargers' opening drive against the Chiefs. On third down, Herbert scrambled and was tackled by defensive end Mike Danna, who landed on his ankle. Herbert limped off the field, and the NBC broadcast showed him grimacing on the sideline while athletic trainers taped his left ankle.

"It was difficult to play with," Herbert said. "It was one of those things that we kind of talked about where we kind of limited some of the runs. I didn't feel great running out the pocket."
