Gibbs did not specify how long, but it certainly doesn't appear Daniels will play in Monday's preseason opener against Denver.
Linebacker Mike Barrow's MRI showed that he has tendinitis in his left knee, but his status for Monday remains uncertain.
Meanwhile, running back Clinton Portis did not practice tonight and it's uncertain how much he'll play, if at all, on Monday.
And linebacker LaVar Arrington missed all day with an injured calf, but trainer Bubba Tyer said he expects him to play Monday.
Then there's right guard Randy Thomas, who rested his knee earlier this week. But when he returned, he pulled a muscle in his side. He'll be fine, but it's just another injury to deal with. Even corner Rashad Bauman missed tonight because of a strained hamstring.
''We've been fortunate that they haven't been major things,'' Gibbs said.
At least there was one positive: receiver Taylor Jacobs was in full pads for the first time in several days.
. . . The Redskins practiced their game day routine tonight in this practice, which was closed to all but select media. They ran practice as if it were a game, going over kickoffs, extra points and even taking a halftime break.
. . . Meanwhile, two of Gibbs' grandchildren wandered around the track with his wife. Cute kids.
. . . The receivers have a nickname for rookie John Standeford -- Sunshine, the same nickname of the white receiver in Remember the Titans.
. . . Kenyatta Jones replaced Randy Thomas at right guard tonight.
. . . Lemar Marshall replaced LaVar Arrington at weakside linebacker.
. . . Earlier in the day, several Redskins and Gibbs taped messages to be sent to the troops in Iraq, courtesy of the Navy and the Marines.
. . . For what it's worth, here was tonight's first unit on kick coverage: Garnell Wilds, Todd Franz, Antonio Pierce, Kevin Mitchell, Mike Sellers, Billy Strother, James Thrash, Andre Lott, Ifeanyi Ohalete and Ralph Brown. But it might give you a clue as to who might win roster spots. Remember, special teams coach Danny Smith will pick at least several players.
. . . Marshall had the night's best hit, knocking over John Simon on a pass over the middle.
. . . Sutlan McCullough had some problems picking up the blitz, a big reason he's in trouble. Linebacker Billy Strother blitzed, pulled up at the last minute and still knocked back McCullough, trying to stop him.
. . . Defensive coordinator Gregg Williams is strict. Because these were game-like conditions, he wanted the players on the sideline to be off the field. Williams told them if they didn't get back, they would run: ''It won't take you long to figure that sh-- out,'' he told them.
. . . The play of the night happened to be the last play. Wilds intercepted a Gibran Hamdan pass on the sideline, knocking it in the air and grabbing it. Then he raced down the sideline. Corner Fred Smoot, who was on the sidelines, raced downfield to mimic a celebration, hugging Wilds.
. . . Wilds had earlier deflected a Patrick Ramsey pass to receiver James Thrash.
. . . End Regan Upshaw has had good pass rushes against the backups. But with Daniels out he'll be starting. This will provide him a good chance to show he can still play. He remains one of the most upbeat players on the roster.
