Dareus (suspension) has opted to leave the Bills in order to receive treatment. "After careful consideration of recent events within my life, I have made the decision to enter a rehabilitation facility," he said in a statement. "I feel this is the best decision for me, my family and my teammates as I move forward with my career. I appreciate the support of my teammates and the Bills organization through this process."
Earlier this week, Dareus received his second suspension for a violation of the NFL's Policy and Program for Substances of Abuse. Among other issues in his personal life, he'll extend his time away from the team with the aim of getting on the straight and narrow. If the defensive tackle indeed comes back to the Bills with a different state of mind, his pass-rushing prowess will be valuable, as he's notched 31.5 sacks in 78 career games.
Lawson (pectoral) may be facing a one-game suspension for a domestic violence incident, Tim Graham of the Buffalo News reports.
The nature of Lawson's offense is unclear, as violations of the NFL's domestic violence policy are supposed to result in a minimum suspension of six games. The veteran outside linebacker was just activated from the Non-Football Injury list on Tuesday, after tearing his pectoral while lifting weights in the offseason. Between injuries and suspensions, the Buffalo front seven is already looking severely depleted.
Ragland's knee has too much swelling for a clear diagnosis to made right now regarding the injury he suffered during last Friday's practice, NFL.com reports.
Ragland had an initial MRI that revealed what is believed to be a partial ACL tear, but was slated to get a second opinion Monday. However, since his knee is still pretty swollen, coach Rex Ryan could not give an update on his condition following practice. As a result, Ragland's situation will have to continue to be monitored, but Buffalo's signings of veteran linebackers Brandon Spikes and David Hawthorne on Sunday seem to indicate Ragland could be slated for an extended sideline stint.
Nkemdiche (ankle) is expected to play in Sunday's preseason game against the Texans, the Cardinals official website reports.
Head coach Bruce Arians said Nkemdiche could get extensive playing time to make up for his absence through training camp and the first two weeks of the preseason. The first-round rookie has probably missed out on any shot he might have had to push for a starting job, but he still has time to earn a key role in Arizona's d-line rotation.
Fitzgerald (knee) wasn't expected to practice Thursday but was seen in pads prior to drills, Josh Weinfuss of ESPN.com reports.
Fitzgerald may have been able to change the mind of head coach Bruce Arians, who has been the driving force behind holding out the wide receiver as he tends to a slight MCL sprain. Individual drills would be a good start Thursday, but there's no need for Fitzgerald to push his luck with more than two weeks remaining before the regular season opener.
Okafor has opted to avoid surgery and play with a torn biceps, Ian Rapoport of NFL Network reports.
Okafor sustained the injury in Tuesday's practice, the second such torn biceps in his three-year career. In 2013, surgery was ordered up for the then rookie, but examinations may have revealed that the tear was less severe than three seasons ago. The pass rusher has totaled 10 sacks the past two campaigns, while logging 66 and 58.5 percent of the defensive snaps, but the addition of Chandler Jones along with the injury could very well result in a scaled-back role.
Brown (concussion) was removed from practice early Thursday, Josh Weinfuss of ESPN.com reports.
One day removed from missing practice due to a headache, Brown took the field Thursday in a no-contact yellow jersey, as he did both Sunday and Monday of this week. While his early departure may have been planned, the fact that his symptoms can be traced to a concussion doesn't bode well for immediate clearance from the NFL's protocol for head injuries.
Jenkins (hand) returned to practice on Sunday, Mike Jurecki of Fox Sports 910 reports.
Jenkins had surgery for a broken hand at the start of August. He was expected to miss anywhere from 2-to-3 weeks, so his return Sunday appears to be on the early side of that original projection. Jenkins will have to battle for a role as a depth option at cornerback for the upcoming season.
