The San Diego Chargers placed rookie cornerback Jason Verrett on season-ending injured reserve, the team announced Saturday.

Verrett, a first-round draft pick, had 19 tackles and one interception in six games (four starts) this season. He has been dealing with a shoulder injury four about a month, and aggravated the injury three weeks ago. He had already been ruled out of Sunday’s game against the Oakland Raiders.

Brandon Flowers and Shareece Wright are considered the Chargers’ top cornerbacks now that Verrett is done for the season.

Also, the Chargers activated outside linebacker Melvin Ingram from injured reserve/designated for return and signed rookie safety Adrian Phillips. In addition, the Chargers released linebacker Cordarro Law.
