The St. Louis Rams have released Kellen Clemens.

Clemens was important in helping Sam Bradford learn Brian Schottenheimer's offense.

The Baltimore Ravens have cut Curtis Painter.

Painter started several games last season for the Colts.

Tyrod Taylor will backup Joe Flacco at quarterback for the Ravens.

The Dallas Cowboys cut Adrian Hamilton on Friday.

Hamilton, who went undrafted out of Prairie View A&M, exhibited good ability in rushing the quarterback. But the Cowboys parted ways with Hamilton due to his inability to contribute on special teams.

Hamilton was impressive enough in getting to the quarterback, however, that he could end up quickly on another team's roster.

The Minnesota Vikings have released Sage Rosenfels in what was a surprising move.

McLeod Bethel-Thompson will be the Vikings' third-string quarterback behind Christian Ponder and Joe Webb.

The Vikings agreed to a deal with Rosenfels in March with $500,000 in guaranteed money.

The Carolina Panthers have acquired special teams star Colin Jones from the San Francisco 49ers for a seventh round pick.

Jones was a sixth round pick out of TCU in 2011.

Carolina showed interest in signing Jones last season when he was on the 49ers' practice squad.

Jones finished the season with eight tackles and seven "big plays" as graded by special teams coordinator Brad Seely.

The Miami Dolphins have taken calls from teams asking about Matt Moore.

Moore is currently backing up rookie Ryan Tannehill. As of Friday afternoon, injured veteran David Garrard was also still on Miami's roster.

The Dolphins will lack a proven quarterback behind Tannehill if they move Moore.

The Patriots surprisingly cut Deion Branch and Brian Hoyer on Friday, according to sources.

Dan Koppen will also be let go.

Branch, 33, spent parts of six seasons with the Patriots, registering 312 receptions for 4,152 yards and 24 touchdowns. He re-signed in March after catching 51 passes for 702 yards and five touchdowns last season.

DeMarcus Ware strongly considered retirement in 2009 when he had a serious neck injury.

Ware is considered one of the NFL's two or three best defensive players, being voted to six Pro Bowls since he was the 11th overall pick by the Dallas Cowboys in the 2005 Draft.

"You never think that you'll be the guy who's on the stretcher," said Ware. "It's usually a special teams guy, because they have those big impact hits. But the guys on offense and defense, we don't have enough speed built up to have that impact. When I went down, everything just stopped. I thought, "Why am I here?" I actually thought that my body was moving. I thought I was moving my arms, I thought I was moving my legs. But I wasn't. I couldn't move. Mentally, I was moving. But physically, I wasn't. I'm sitting there, just thinking. I was thinking, "I'm that guy." Everyone was watching me, just lying there, unable to do anything. I felt embarrassed, actually. They strapped me up, and I wasn't able to move my neck or arms or legs, but I said, "I'm alright. I'm alright." Then it finally hit me when they took my facemask off. When they took that facemask off, they took something out of me."

Ware considered walking away from the game, but not due to the physical pain.

"No, because I was scared. I was so scared. I started thinking about my family. I thought, "I might have to give football up." I really thought I might have to retire, because I just couldn't imagine going through something so traumatic again."

The Cleveland Browns have released Seneca Wallace.

Brandon Weeden and Colt McCoy were ahead of Wallace on the depth chart.

The Miami Dolphins have cut wide receiver Clyde Gates.

Gates was a fourth round pick out of Abilene Christian in 2011.

Gates ran an excellent 40 at the combine, but was a raw prospect.
