Offensive lineman Kili Lefotu was released from the hospital on Friday, but it's still uncertain what caused his illness last Wednesday.
"All of the tests that came back, the doctors feel that he had a seizure, but the tests weren't conclusive," Redskins director of sports medicine Bubba Tyer said on Friday. "We are just going to keep an eye on him and slowly get him back."
The team had targeted Tuesday as a possible date that Lefotu could return to practice.
On Friday evening, Lefotu was back at the National Conference Center, where the team is staying during training camp, with his fiancé.
"He's feeling better, but he's just a little weak from his two days in the hospital," Tyer said. "He said he really didn't eat much."
Lefotu, a 6-5, 315-pound rookie out of Arizona, will not accompany the Redskins to Cincinnati for this Sunday's preseason game.
Lefotu was first hospitalized on Wednesday evening. Team officials first noticed that he was absent from Wednesday's practice and rushed over to his dorm room to locate him. Lefotu was conscious when team officials found him, but then the 6-5, 315-pound lineman "just passed out," Tyer said.
Lefotu was immediately transported to a local hospital to undergo tests.

#### -- TOUGH LINDSEY
Redskins linebackers coach Dale Lindsey makes his players earn praise. Listening to him talk after a recent training camp practice, you get the impression that he is not happy with any of his young linebackers.
On Chris Clemons: "Chris has good and bad days. The thing we want out of Chris is more consistency, we want him to be more physical and we want him to be a better special teams player. Not having those three things this year is unacceptable for Chris. He has enough talent do all three of those things."
On Robert McCune: "[His development] is not where you want it. Robert turned out to be a good special teams player last year, and if you're a backup linebacker here, you have to be a good special teams player. We expect him to rise this year at middle linebacker. Right now, I don't see him as where we want him."
On Rocky McIntosh: "[His development is] typical. He's coming in with good athletic ability, but his mind is overloaded because of all of the things he has to learn and all of the things he has to do. When he does know what he's doing, you can really see the good athletic ability that he has."
On Kevin Simon: "He's a typical rookie, too. He's overloaded, too. He needs to be a little sharper in his calls and making his adjustments. We'd like him to be a little more physical than he is right now. He's growing."
