The Los Angeles Chargers were already expecting wide receiver
DJ Chark Jr. (hip) to sit out in Week 1, but his absence will last longer after the team
placed him on injured reserve, according to NFL Network’s Tom Pelissero. Chark will now sit out the first four games of the season. The Chargers signed TE Eric Tomlinson to the active roster and added LB Shaquille Quarterman from the practice squad for Sunday’s game against the Las Vegas Raiders.
