TEMPE, Ariz. Detroit Lions Jerseys . -- 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."

At a news conference Tuesday where it was thought that the fiery Schallibaum may be shown the door after a dismal finish to the Major League Soccer season, team president Joey Saputo said no decision has been made on whether the Swiss Volcano will be back in 2014. INDIANAPOLIS -- Dallas Clark never took his eyes off the screen as a video tribute played highlights from his time in Indianapolis. The standout tight end retired from the NFL after 11 seasons Wednesday and when he stepped to the podium at the teams practice facility, he could hardly keep his composure. "Obviously you should have showed the video afterward," Clark said after taking a long pause to gather himself. "My wife told me to keep it lighthearted. I just dont know how to do that because this place and these fans and everyone here mean so much to me." He retired as a member of the Colts, the team that drafted him in the first round in 2003. Its the place where he won a Super Bowl with Peyton Manning in 2006 and spent the first nine years of his career. Clark played for Baltimore last season and for Tampa Bay in 2012. He was released by the Colts in 2011 after the team finished 2-14 and missed the playoffs for the first time in 10 years. Clark signed with Indy just long enough to announce his retirement, though Colts owner Jim Irsay wisecracked that there was no signing bonus this time. "Theres a lot more meaning behind it than numbers," he said. "Its really a great moment when you have a chance to have somebody come back to town." Clark is Indys all-time leader in tight end touchdown catches (46) and receptions (427). He finished second in yards receiving (4,887) and 100-yard games (seven). Clark set single season records with the Colts with 100 receptions and 1,106 yards in the 2009 season. In 2007, he had 11 TD catches. The Colts won at leeast 12 games for seven consecutive seasons and made eight straight playoff appearances leading up to Clarks final season in Indy, before his release and the release of other veterans, including Manning.

"You cant write this, you cant make this up," Clark said as he thanked everyone from team doctors and equipment staff, to former Colts coach Tony Dungy and former team President Bill Polian, who drafted him with Indys first-round pick in 2003. "Nothing but love," he said to a crowd that included Reggie Wayne, Robert Mathis and Adam Vinatieri. "For us to go do what we do, theres so many people. Im not going to stand here and think I did it myself because that would be a boldface lie." Wayne was drafted by Indy in 2001 and played alongside Clark each year he was with the Colts. "From day one, he came in with a mission and focused in on it and he locked in on it and within that first year, he came in and made some plays and I knew he was going to be major, major contributor to this offence," Wayne said. "He was that last piece of the puzzle and without Dallas, I dont think we win as many games as we did." Clark got emotional when thanking the teammates hes had throughout his career. "When you have 52 men in the locker room giving everything that they have for one goal, special things happen," he said. "For us, we won like it was like, thats what you do. Until I went to other places, it was like, not everyone gets it. Not everyone can do what we did. Thats the reason why it was so special."
