TEMPE, Ariz. Cheap Adidas NMD 2019 . -- Outside linebacker John Abraham has left the Arizona Cardinals and is considering retiring from the game. Cardinals coach Bruce Arians said on Wednesday that Abraham, the games active sacks leader and ninth on the NFLs career list with 133 1/2, has been granted a leave of absence. The team obtained a roster exemption, using it to re-sign linebacker Marcus Benard. The 36-year-old Abraham sustained a concussion in Monday nights 18-17 season-opening victory over San Diego. But Arians said he had a long talk with Abraham on Tuesday and the concussion was not the main reason the player was considering leaving the game. Arians said that while Abraham goes through the NFL-mandated concussion protocol, he "will determine if he wants to continue playing football, whether his hearts still in it and he has the fire and desire to do it." Abraham, in his 15th NFL season, has five days under NFL rules before the Cardinals must either reinstate him or declare him out for the season. He missed nearly all of training camp to, as he later confirmed, undergo rehabilitation treatment for an alcohol problem. The rehab stint came after he was arrested in suburban Atlanta and charged with drunken driving. "I think with all the things that hes gone through in the last month, hes got a lot of things outside of football that hes never dealt with before," Arians said. "There are some people that can help him in that regard. Im not one of them." Arians said that "there are things Im not clinically smart enough to know what depression is and things like that so theres many issues that could be involved." Abraham, who had no tackles against the Chargers, expressed concern about whether he was hurting the team, Arians said. "If that game on Monday night football and that atmosphere didnt have you flying around like always or more, then somethings missing," the coach said, "and thats basically what he reflected to me. He said There were times in that game I wasnt in it and its not fair to my teammates. Ive got to decide if this is still what I really want to do." Abraham is in the second year of a two-year contract. He led the Cardinals with 11 1/2 sacks last season and made the Pro Bowl for the sixth time. He needs nine sacks to pass Michael Strahan for fifth on the career sacks list. Abraham played six seasons for the New York Jets and seven for the Atlanta Falcons before coming to Arizona as a free agent. "Were all hoping and praying for him, hoping he returns back to normal," quarterback Carson Palmer said. "Obviously, were going to miss him and miss his production. Somebody else has to step up. Coach Arians motto is next man up. Somebodys got to find a way to replace his production." The injury is another significant loss for the Arizona defence. Defensive tackle Darnell Dockett tore an ACL in training camp and is out for the season. The team already was without its two standout inside linebackers from a year ago. Karlos Dansby left for Cleveland via free agency and Daryl Washington is suspended for the season for violating the NFLs substance-abuse policy. Arians said Abraham told him that this was his first concussion, something that teammate Lorenzo Alexander doubts is true. "Playing this game everybodys had multiple concussions. Whether or not theyre diagnosed is something totally different," Alexander said. "Im pretty sure hes had multiple concussions throughout his career like we all have. This was probably his first documented one." Arians said Sam Acho would move into Abrahams spot. "Johns a leader. Hes a guy that leads by example," Acho said. "You look at his film, the way he plays the game. I watch Johns film to see what I can do better." Adidas NMD Factory Outlet .

ORCHARD PARK, N.Y. -- Bills defensive tackle Kyle Williams had a few cautionary words of advice for Marcell Dareus, in welcoming his teammate back to practice Tuesday. Its time, Williams said, Dareus realized he has put his young and promising career in jeopardy after being charged in two separate arrests last month involving drug possession and a car accident. "Im hoping that this is kind of a watershed moment for him, because hes at a pivotal point," Williams said after Dareus reported for the start of the Bills three-day mandatory minicamp. "Hopefully, its to a point where its kind of an epiphany, and he comes alive and turns the corner and does his best." Williams, a team captain, is taking a tough-love approach with Dareus, a player hes spent the past three years mentoring. "I think hes heard (advice) from a lot of different levels, whether it be from his teammates or coaches, and Im sure the front office," Williams said. "So if you cant get it from those three levels, maybe youre not going to get it." Dareus, the Bills 2011 first-round draft pick, returned to practice for the first time since he and coach Doug Marrone agreed that the player take two weeks off to sort out his legal problems. Its unclear what Dareus has been doing during his time away. The Bills announced before practice that Dareus will not be made available to reporters this week so that he can focus solely on football. Dareus was escorted off the field by a team official following practice. Hes been off since May 30. Thats when shortly after participating in a voluntary practice, Dareus crashed his 2012 Jaguar into a tree near a busy suburban Buffalo intersection after allegedly racing teammate Jerry Hughes. Dareus was charged with reckless endangerment and ticketed for several traffic violations, including drag-racing. Dareus was scheduled to appear at Hamburg Town court on Tuesday, but that was pushed back to July 1 in part so that he didnt miss practice. Four weeks earlier, Dareus was arrested in his native Alabama and charged with possession of synthetic marijuana aand drug paraphernalia. Cheap Mens Adidas NMD Shoes. Rod Giddens, the attorney representing Dareus in Alabama, said hes still awaiting word from prosecutors as to whether theyll accept a plea deal in which Dareus entered a pre-trial intervention program to have the charges reduced or dismissed. Dareus troubles actually come from the end of last season when he was benched during each of the Bills final two games because he was late for team meetings. General manager Doug Whaley intends to meet with Dareus following the Bills final practice on Thursday, when the team takes a month before opening training camp July 20. "Ill just have a little sit-down with him when we leave, so everybodys on the same page," Whaley told The Associated Press. "The thing right now is hes back focused straight on football. Its great that hes back. And I think he thrives in a situation like this where its all football." On the field, Dareus returned to his familiar starting spot alongside Williams. In one team drill during the non-contact practice, Dareus showed off his power and speed by bullying past guard Kraig Urbik to break up a potential pass. On the next play, Dareus spun off Urbiks block and filled the hole to stop a run. Coach Marrone has stuck by Dareus, while expressing disappointment in saying the player has made "some poor decisions." "I just want to make sure that Im clear that everyone understands that I believe in Marcell, and I will do everything I can to make sure that we can get him on the right track," Marrone said two weeks ago. "Im going to do everything I can to help a 24-year-old man make better decisions."
