The Chargers placed WR D.J. Chark (hip) on IR. He's out for at least the first four games of the season. Chark looked like the favorite to open the season as Los Angeles' starting outside WR opposite Josh Palmer, but WR Quentin Johnston will now get another crack at that job. We're not very optimistic Johnston will take advantage, but he's worth monitoring in tomorrow's opener vs. the Raiders. Chark can be dropped in all redraft leagues.
