July 30 (UPI) -- Wide receiver Mike Williams will miss his rookie training camp due to a back injury.
The Los Angeles Chargers put the Clemson product on the active/physically unable to perform list on Saturday, along with safety Darrell Stuckey and cornerback Jason Verrett.
Los Angeles announced that Williams visited with doctors on Saturday and will continue to progress on Dr. Robert Watkins' plan.
"He will rehab and strengthen his back and is not expected to practice during training camp," the Chargers' team statement said.
Verrett is rehabbing from a knee injury last season. He is working on the side this week and will be re-evaluated next week. Verrett isn't expected to miss much time. Stuckey is day-to-day as he rehabs his knee.
Williams had 1,361 yards and 11 touchdowns on 98 receptions in 15 games last season for the National Champion Tigers. The 22-year-old would miss the first six games of the season if the Chargers put him on the reserve/PUP list.
Sources with direct knowledge of the situation told NFL Network that surgery was on the table 3-to-4 weeks ago, but it is now off the table.
Williams has had two epidurals on the herniated disk in his lower back, but is "feeling better" according to reports.
Williams has not practiced since the first day of rookie minicamp.
