Washington Redskins safety Brandon Meriweather said that his recovery from surgery to repair a torn anterior cruciate ligament continues to progress positively and that he is on schedule to return to action by the start of training camp. Meriweather signed with the Redskins last offseason with the anticipation of starting at strong safety. But he sprained ligaments in his right knee in the preseason, aggravated the injury leading up to the season opener and then again in Week 4, keeping him sidelined until Week 11. Once finally on the field, Meriweather had an immediate impact, recording seven tackles, two pass breakups and an interception in the first half of Washington’s game against Philadelphia. But early in the second quarter, Meriweather tore the ACL in the same knee and was lost for the season. He has spent the offseason rehabbing at Redskins Park and is encouraged by his progress. “Everything’s going good,” Meriweather said in a phone interview. “I’m on schedule. Everything’s positive.” Meriweather began running in the pool and on the treadmill roughly two months ago. Two weeks ago, he began running on grass. The Redskins began their offseason conditioning program two weeks ago, and will begin offseason practices (organized team activities, or OTAs) on May 20. Meriweather wasn’t sure if he would be on the field for any of the walkthrough portions of those practices, saying that decision was up to the team’s trainers. However, a person with knowledge of the situation said that Meriweather is expected to continue his rehabilitation work on the side, and wouldn’t likely take the field with his teammates until training camp, which begins in late July.
