Ravens defensive tackle Arthur Jones and nose tackle Brandon Williams aren't practicing today at the start of the work week for undisclosed reasons.
Jones has been sidelined for a week with something coach John Harbaugh characterized as a "personal health issue," that's not regarded as serious.
There's been no injury reported for Williams, a third-round draft pick from Missouri Southern.
Meanwhile, rush outside linebacker Pernell McPhee has returned to practice after dealing with soreness in his knees for most of the preseason.
Wide receivers Deonte Thompson (sprained left foot) and LaQuan Williams (strained hamstring) aren't practicing as well as center Ryan Jensen (foot surgery) and tight end Dennis Pitta (hip surgery)
The Ravens have formed their practice squad, signing former Maryland tight end Matt Furstenburg, offensive tackles Jordan Devey and J.J. Unga, safety Omar Brown, linebacker Brandon Copeland (Gilman), defensive tackle Cody Larsen and center Reggie Stephens.
All of those players were with the Ravens during training camp and were released during the final roster cuts.
As the practice squad guys were jogging onto the field a few minutes late after signing their contracts, they were greeted with a slow clap and cheers from teammates. Ravens coach John Harbaugh quipped: "Congratulations, now get your butt out here."
