Herbert was more of a bystander during the portion of practice open to the media, performing some handoffs to running backs, but did not do any throwing.
Chargers coach Brandon Staley said Herbert is day-to-day as one of three players listed as a limited participant on the team’s practice report. The star quarterback was injured by a hard hit in the fourth quarter of last week’s 27-24 loss to the Kansas City Chiefs.
Herbert only missed one play after taking a hit from Kansas City defensive lineman Michael Danna on a completion to Gerald Everett on Thursday, but was clearly in discomfort for the remainder of the contest.
''He's had a lot of rest since the last game, but I think the nature of the week is truly going to be a case-by-case, day-by-day basis,'' Staley said. ''We're just going to see where his comfort level is, and truly trust him and let him be the guide of where we're at, and make sure that we are prepared either way.''
Staley said the decision to play Herbert Sunday against the Jacksonville Jaguars begins with the quarterback himself.
"It will start with him and then obviously him feeling good about what the medical team feels like is best, him weighing the options and then us making a good decision," Staley said.
The Chargers have had issues with injured quarterbacks before.
The doctor caring for Herbert is being sued for medical malpractice by former Chargers quarterback Tyrod Taylor, who is seeking at least $5 million in damages.
In 2020, Taylor suffered a rib injury against the Cincinnati Bengals and a team doctor then punctured Taylor’s lung while attempting to give him a pain-killing injection. Taylor was taken to a hospital and Herbert was thrust into his first NFL start less than a minute before kickoff, with Taylor never recapturing his starting role.
The lawsuit was filed in Los Angeles County Superior Court in May 2021 and a trial was scheduled to begin in November, but has been moved to June 2023.
In two games this season, Herbert is 59-of-82 for 613 yards with six touchdowns and one interception.
