Humphries hyperextends knee, Palmer talks about day off

GLENDALE, Ariz. (AP) Arizona Cardinals starting wide receiver Michael Floyd left practice Wednesday with an injured left hand.

The Cardinals didn't reveal the severity of the injury that occurred near the goal line at University of Phoenix Stadium. He was in obvious pain when he walked off the field with a trainer.

Entering his fourth NFL season, the 6-foot-2, 220-pound Floyd has been the main downfield threat for a talented group of Arizona receivers that includes Larry Fitzgerald and John Brown.

Floyd, a first-round draft - 12th overall - out of Notre Dame, caught 47 passes for 841 yards and six touchdowns last season, down from his breakout 2012 year, when he caught 65 passes for 1,041 yards and five scores.

Jaron Brown took Floyd's place with the first unit the rest of practice.

Later in the practice, guard John Fullington was taken off the field in a cart with a left knee injury.

The Cardinals got some good news on injuries earlier in the week when an MRI determined that he only hyperextended his left knee in practice Tuesday.

Humphries, trying to unseat Bobby Massie as starting right tackle, was one of 13 players sitting out Wednesday's practice with injuries.

On Tuesday, Carson Palmer took a training camp day off when healthy for the first time in his NFL career, although he said he didn't like it.

''It was something that was set in stone months ago,'' the quarterback said Wednesday in his weekly meeting with reporters. ''It was something I argued with for probably six weeks and then just gave up because I realized I was getting nowhere with it.''

Palmer, 35, is coming off surgery to repair a torn ACL and he acknowledged the day off might have done him good.

''I think so,'' he said. ''I won't admit that to them but I understand what they're thinking.''

He said the plan is to have him take off every fourth or fifth day. On Wednesday, backup quarterback Drew Stanton had the day off. Stanton also is coming off a knee injury, although less severe than Palmer's.

Palmer took a tumble in Monday's practice, the first of the camp for the team in pads, but said it never fazed him.

''It looked a lot worse obviously than it was when I saw it on film,'' he said. ''I didn't really realize what happened, especially because we were in a two-minute drill, and you're focused on what happened on that play, and then what you're going to do on the next play, and really didn't think twice about it.''

Safety Tyrann Mathieu pushed running back Kerwynn Williams into Palmer's legs, knocking the quarterback over.

Palmer said Mathieu has checked on him a number of times since.

''He was more scared than I was,'' Palmer said, ''a little more nervous than I was when it happened.''

Mathieu said Tuesday that ''my heart was in my behind'' when Palmer went down.

New to the injured list, along with Humphries, were guard Earl Watford (knee), linebacker Darryl Sharpton (hip flexor), running back Marion Grice (hamstring) and tight end Ted Bolser (knee).
