The Ravens signed free agent cornerback Frank Walker to a two-year agreement today.

Walker, 26, was a dime back last season for the Green Bay Packers and previously played four seasons with the New York Giants (2003-06). He is expected to compete for the team's third corner spot behind starters Chris McAlister and Samari Rolle, according to the Ravens.

"Ozzie's (Newsome) plan is to add valuable depth to the secondary this offseason, and he did that with Frank. Frank can be a quality nickel for us, and he'll add athleticism and toughness to our special teams. It's a good signing for us," Ravens coach John Harbaugh said.

"Frank brings us some flexibility to the secondary," director of player personnel George Kokinis said. "He plays outside, the nickel spot and the dime spot. ... He's also done a nice job on special teams. As a core member of the Packers' special teams unit, he produced. We need guys that can step up and fill roles on defense and special teams, so he can help us. ..."

The Ravens also signed free agent kicker E.J. Cochrane today. Cochrane (Montana State) previously spent parts of the 2006 preseason with the Philadelphia Eagles and Green Bay Packers, and also participated in Philadelphia's 2007 training camp.

"E.J. is a guy that we've watched for a while," Kokinis said. "He had been at some kicking camps that we went to. I think he has a strong leg and gets good height on the ball and good hang time. Over the last few years, he's really worked on his consistency and accuracy. He's matured a little bit. Early in his career, you're just thinking of him as a kickoff guy, but the last couple of years, he's refined his technique."
