Add Denarius Moore to the list of hobbling Raiders wide receivers.
Moore was wearing a boot on his right foot Wednesday as he recovered from an injury suffered in Sunday's 27-21 win over Minnesota. Moore left the game at one point after a punt return but later returned to the field.
Of the 10 players who did not participate in practice, four were wide receivers: Moore, Jacoby Ford (foot), Darrius Heyward-Bey (neck) and T.J. Houshmandzadeh, whose wife had a baby. That left only Chaz Schilens, Louis Murphy and practice squad player Eddie McGee on the field for practice.
"It's a concern," coach Hue Jackson said, "but I think we have a chance to get some of these guys back toward the end of the week."
Houshmandzadeh should be back for Sunday's game against the Chicago Bears, but Jackson was nonspecific about the others. Ford, Jackson said, was not yet out of his boot but was expected to be soon.
"It makes it difficult," quarterback Carson Palmer said. "You don't get the same guys on the field from the week before, and the rhythm and timing slows down a little bit. So we have our work cut out for us."
Murphy is eager to contribute, as he has struggled since having sports hernia surgery during training camp. He has one reception for 23 yards -- this after being the Raiders' leading wide receiver over the last two seasons with 75 receptions for 1,130 yards and six touchdowns.
"I've talked to Coach Jackson and
Campbell, out since Oct. 16, has not yet begun throwing, Jackson said.
"I think he tried a little bit, and it just wasn't there," Jackson said. "But I think he's getting there."
Cornerback Chris Johnson was on the practice field and was limited but said he wouldn't be ready to play against Chicago. Also limited were safety Mike Mitchell (ankle), safety Michael Huff (ankle) and fullback Manse Tonga (knee).
Place-kicker Sebastian Janikowski, who has been slowed by a left hamstring injury, was not listed on the report, nor was linebacker Rolando McClain, who has been battling an ankle injury.
McCann was active against Minnesota and played on special teams, including a kickoff return of 36 yards.
