Injuries Are a Sore Spot for PortisSwollen Knee Hampers Redskins Tailback Year After Shoulder, Hand WoesBy Jason La CanforaWashington Post Staff WriterThursday, August 2, 2007; E01When training camp began Friday, tailback Clinton Portis was glowing. His surgically repaired shoulder and hand were pain-free, and Portis believed an offseason bout of right knee tendinitis was finally behind him. "I feel great. I'm excited. I feel healthy," Portis said, eager to leave his lost 2006 season behind.But less than a week later, questions about his health have surfaced. Portis, 25, missed a second straight day of practice yesterday and will continue to strengthen and have treatment on his swollen knee, likely remaining on the sidelines until at least next week. Portis, whose tendinitis was diagnosed in May, was limited to eight games last season. He suffered a partial dislocation of his shoulder on the opening series of the preseason and later broke his hand. He never resembled the runner who set a franchise record with 1,516 yards in 2005.Backup Ladell Betts emerged as a competent feature back, providing security at the position and challenging Portis to prove he is still among the NFL's top runners this season. Given Portis's relatively slight frame by NFL standards (a generous 5 feet 11, 223 pounds), his lengthy layoff and his recent injury history, that might become a difficult task. The Redskins are committed to getting Portis fit by the start of the regular season, and they believe that if handled properly, the recurrence of tendinitis will not be an ongoing concern. The team is viewing his condition as a minor malady, but in a collision sport and at a position that puts enormous strain on the knees, it clearly warrants monitoring."Clinton's got a little soreness in his knee, the one he had patellar tendinitis in," said Bubba Tyer, Washington's director of sports medicine. "We're going to modify his workouts some and concentrate a little more on strengthening work and conditioning work without the trauma of practice -- cutting and turning. He felt a little discomfort in the cutting and turning and pivoting on his leg, so we'll get it a little bit stronger and then we'll get him back out there."Tyer is keeping a close eye on wide receiver Santana Moss, too. Moss's workload was curtailed yesterday because of a recurrence of discomfort in his groin. Moss was hampered by hamstring problems last season, developed a hip flexor strain this offseason, and, according to Tyer, the groin issue returned this week as a result of compensating for the issues with his hip. Moss set a franchise record for receiving yardage in 2005 and his health is important to the offense.Portis, never a huge proponent of preseason activities, brought a renewed enthusiasm to training camp, one the coaches hope will not wane as his time on the sidelines increases. He had said he would complete any preseason assignment sent his way. For as good as Portis felt, however, playing basketball, running sprints and passing running tests, Tyer said the athletic trainers anticipated some minor setbacks as Portis's activity increased. He is all but certain to miss Saturday's scrimmage in Baltimore."As much as he thought he was ready to do, it's two-a-days and it's football," Tyer said. "And it's a lot more cutting."Coach Joe Gibbs said the team will continue to err on the side of caution with Portis -- "We're just trying to do the best job we can with that thing," he said -- and running backs coach Earnest Byner aims to keep Portis in good spirits. "A lot of the healing process is mental," Byner said. "We want to make sure he stays upbeat, too, and stays emotionally challenged and feels good about himself."
