Safety Tanard Jackson and offensive tackle Jordan Black participated in their first practice of training camp Thursday with the Redskins.

   Jackson practiced with the second-team defense. He surrendered a long touchdown catch by wide receiver Brandon Banks early in the practice but said later he was pleased with his overall performance for his first time out.

   “I’m getting my legs back under me,” Jackson said. “The first day out, it felt good to be back out there. The most important thing is I didn’t have too many mental errors. I gave up a deep ball early in practice but, you know, it comes with time. I’m happy to be back out there.”

   Jackson had to wait three days, under a provision in the collective bargaining agreement, after being medically cleared Sunday to practice. He began camp on the physically unable to perform list because of a calf injury.

The Redskins signed Jackson in April after he was released by the Tampa Bay Buccaneers and he potentially could factor into the team’s starting competition at safety. Brandon Meriweather and Madieu Williams continue to practice with the starters.  

Black worked with the second-string offense Thursday at right tackle. The veteran was signed this week by the Redskins after being out of the league last season, and was subject to the same CBA provision that kept Jackson waiting for three days to practice. The rule says that all players must begin camp with one day without on-field activities followed by two days without hitting and without wearing pads.

   “It was good,” Black said. “I mean, there’s some rust I need to knock off. There’s some timing stuff, getting off the snap count on time. But it’s easily correctable with time.”

   Tyler Polumbus continues to practice with the starting offense at right tackle in place of Jammal Brown, who is sidelined by an ailing hip and remains on the camp PUP list.
