TEMPE, Ariz. -- Tyrann Mathieu returned to practice for the Arizona Cardinals on Wednesday and said he was optimistic that he would be able to play when the team faces the Vikings in Minnesota.Coach Bruce Arians also confirmed after practice that wide receiver Jaron Brown has signed an extension that puts him under contract through next season.Brown is out for the season with a knee injury.We love him as a football player, Arians said. It looks like hell be fine health-wise, gives him another year. Hes earned it. Really happy for him and its good for us because hes a quality special teams player and a real quality receiver.The signing gives the team some protection should the Cardinals lose wide receiver Michael Floyd, who becomes a free agent at the end of this season.Jarons a guy you dont want to lose, quarterback Carson Palmer said. What he brings to the team, because he can play special teams, he plays every spot at receiver. Hes got speed, hes physical, he catches the ball. He catches 50-50 balls very well. Just a very, very well-rounded receiver.Browns signing was first reported by azcentralsports.Mathieu was limited in practice but said afterward that his shoulder felt fine. He was still wearing a brace on the knee that was surgically repaired late last season but was meeting with the doctor to discuss taking it off, which would greatly aid the mobility that is so crucial to the way he plays the game.Of courses Id rather play without it, he said, but I dont want to do anything that puts me in harms way, so Ill talk to him. Im sure well negotiate something.The defensive back was sidelined with a shoulder subluxation in Arizonas loss at Carolina on Oct. 30 and missed Sundays 23-20 win over San Francisco.He said removing the brace would clear another hurdle as he tries to get back to his aggressive Honey Badger performances of the past.The shoulder injury, he said, was just another challenge.Life frustrates sometimes, Mathieu said. Youve just got to deal with it. Cant get too high or too low. Its just another challenge for me. I embrace all those challenges.The way Mathieu talked, his participation in Sundays game was no sure thing.Ill see how I feel at the end of the week and if Im at 100 percent, or very close to it, Ill play Sunday, he said. If not, Ill hold back. ... Im optimistic I will play. I try to look on the bright side of everything.Mathieu was asked about the perception that hes handling this shoulder setback better than he did such problems earlier in his career.I dont know, he said. From the outside looking in maybe, but its frustrating on the inside, obviously. A lot of noise. You try to tune that out. Just another challenge for me. I embrace it.The Cardinals defense ranks second in the NFL, allowing 295.2 yards per game, but Mathieu said the team doesnt have the swagger it exhibited in last years 13-3 season.At times weve had swagger. We have had confidence, he said. Were just playing inconsistent right now. Weve just got to get that consistency back. Once we get that back, Im sure well be rolling.Theyd better get rolling soon. At 4-4-1, the Cardinals cant afford many more stumbles if they want to challenge for a playoff berth.After Sundays game against a Minnesota team hungry for a win after four straight losses, the Cardinals go to Atlanta to face the NFC South-leading Falcons.Game notes Larry Fitzgerald didnt practice due to knee and ankle injuries but Arians said he remains confident his star wide receiver will play Sunday. ... Palmer had another veterans day off. ...
