Chargers QB Justin Herbert's right leg will be evaluated after X-rays were negative

Chargers quarterback Justin Herbert's right leg will continue to be evaluated this week after it got rolled up on in Los Angeles' 26-3 victory over the Carolina Panthers on Sunday.

Coach Jim Harbaugh said on Monday that X-rays were negative and that there will be more information on Wednesday when the Chargers begin preparations for Sunday's game against the Pittsburgh Steelers.

The Chargers will practice at UNC Charlotte this week with consecutive games in the Eastern time zone.

The injury happened late in the third quarter. Herbert moved up in the pocket as it collapsed, but his lower right leg was rolled up on from behind by linebacker D.J. Johnson as he fumbled the ball at the Carolina 20-yard line.

Herbert walked gingerly to the sideline and pointed to his right ankle while talking to trainers on the bench. He briefly spent time in the medical tent, but did not miss any snaps after he got his ankle taped up. Herbert was 14 of 20 for 130 yards with two touchdowns and an interception. It was his lowest passing yardage total in a full game in five NFL seasons.

"We'll know more the next couple of days, but was able to finish the game and keep moving around on it, so I'm looking forward to it," Herbert said after the game.

Herbert missed two weeks during training camp because of an injury to the plantar fascia in his right foot, but has been full-go in practice during the first two weeks of the regular season.
