ASHBURN, Va. -- On the first day of organized team activities the media was allowed to watch, the Washington Redskins' marquee offseason addition couldn't finish Thursday's practice. Pro Bowl wide receiver DeSean Jackson pulled his left hamstring running a deep route and soon wound up with an ice pack on one of his multi-million dollar legs.
The players don't return to action until Monday and it's unclear if Jackson will be ready to go. However, since training camp doesn't start for eight weeks, neither Jackson, whom the team signed in April after he was surprisingly cut by the Philadelphia Eagles over rumored character issues, nor rookie coach Jay Gruden seemed very concerned about the injury.
"It's just a little tight," Jackson said. "It's not no big issue."
Gruden agreed, terming the injury "a minor pull" before adding that the Redskins will take the "necessary precautions to make sure he's right" since the 5-foot-10, 178-pound Jackson is "no good to us unless he's running very fast."
Before the injury, Jackson had run well.
"It's going good so far, just out here working," Jackson said. "I'm a new familiar face here."
Quarterback Robert Griffin III said that Jackson, "is a talent. Everyone knows that. We've gotten to know him as a guy the past couple months. We're happy with what we know and what we see."
The 27-year-old Jackson acknowledged that "it's a little weird" being teammates with players whom he faced twice per season while with the Eagles, but he's getting used to the idea.
"I've always been a rival with the Redskins, so now being here, everything has been going good, you know, just getting in where I fit in," Jackson said. "My coaches and my teammates support me. That's a great feeling to have. I feel like everything happens for a reason. My next opportunity's here in Washington and I'm looking forward to doing some great things for this team."
Jackson is expected to start opposite Pierre Garcon, who set a Washington record with 107 receptions in 2013.
-- Griffin III's glorious rookie year of 2012 ended with a serious knee injury in Washington's playoff loss to Seattle. The quarterback's less stellar second season ended with him watching from the sideline for the final three games after then-coach Mike Shanahan declared that he had been hit enough behind poor protection.
Since then, Shanahan and offensive coordinator Kyle Shanahan have been fired and replaced by Gruden and Sean McVay -- who are new to those roles -- Griffin has shucked the knee brace and the Redskins added 2013 Pro Bowl pick DeSean Jackson and free agent pickup Andre Roberts to the quarterback's receiving corps.
"I feel really good about we have," said Griffin, who added that he feels 100 percent a year after he missed spring workouts while recovering from knee surgery. "We've got some new additions that can really help us. We're all excited. (Gruden's) seems like it's flowing well. Everybody's fitting in nicely."
Gruden, once a star quarterback in the Arena League, has been impressed with Griffin so far.
"He's done an excellent job as far as command of the huddle, spitting out the play and not having many mentals (mistakes)," Gruden said Thursday. "When you've only played two years (in the NFL) at the quarterback position, you're going to have your growing pains. (But) the great ones will always improve from year to year and learn from their mistakes. He's doing a good job of that.
We're giving him a lot of reps, a lot of good looks and a lot of different concepts. So far he's reacting well. (Wednesday), we had a play and he threw an interception. Today, we got the same, exact defense. He saw it, went through his progressions and made a great throw to (tight end) Logan Paulsen."
-- Strong safety Ryan Clark left Washington for Pittsburgh as a free agent after the 2005 season. Clark's partner on the back end in 2004 and 2005, Sean Taylor, was murdered in 2007 at 24 years old. But Clark still cherishes the memory of playing alongside the emerging star. So much so that Clark is wearing Taylor's old No. 21 during OTAs.
"I won't forget him and I don't want anybody else too," said the 34-year-old Clark, who returned to the Redskins as a free agent in April. "As long as I'm (still) getting an opportunity to play this game, this will be my way of remembering him."
Receiver Santana Moss, along with defensive end Kedric Golston the only other Redskins who played with Taylor, was glad to see Clark honoring their late friend.
"I appreciate it," Moss said. "Anything to keep his memory around. I look out there and it almost gave me that old thought of Sean being back there."
-- Tanard Jackson is in uniform for the first time in nearly two years having been suspended by the NFL for his third substance abuse violation on Aug. 31, 2012, a sentence from which he wasn't released until this month.
"It was long," said the 28-year-old Jackson, who started all 56 games he played in for Tampa Bay from 2007-11. "I'm keeping the good people around me who was there during those tough times."
Gruden said that Jackson doesn't seem that rusty despite the long layoff.
"He doesn't look like he's been away for two years," Gruden said. "He's done a good job. Mentally, he's into it. Physically, he's in good shape, better shape than we were thinking he would be. People make mistakes. He had an unfortunate incident or two.
"We're going to give him a shot. This is probably his last go-round here so he's going to the most of it, I'm sure. He's a good person, a good player and hopefully he'll learn from his mistakes off the field and perform at a high level like we know he's capable of."
