An MRI exam Thursday of Albert Haynesworth's irritated knee revealed no structural damage, and the Redskins are hopeful the Pro Bowl defensive lineman will be at full strength soon, people familiar with the situation said. Haynesworth missed the 13th practice session of the Redskins training camp Thursday morning. The knee problem, which developed late last week, has prevented him from taking the conditioning test coach Mike Shanahan requires of players who missed more than half of the offseason workouts. "We're giving him an MRI today because his knee has been a little bit sore, more sore than it has been in the past," Shanahan said, speaking before Haynesworth underwent the MRI. "In the past, every third or fourth day it'd be a little sore, according to the trainers. But now it's been a couple days consistently sore...We're going to MRI it, see if he's okay and then we'll go through the rehab work to get it stronger." Haynesworth spent the entire morning practice session on the field, watching his teammates. He then spent more than 20 minutes after the practice working with defensive coordinator Jim Haslett, defensive line coach Jacob Burney and strength and conditioning coach Ray Wright.
