Inside linebacker Keyaron Fox has wasted little time acclimating himself to the Washington Redskins, the team that signed him as a free agent two weeks ago.

On the same day that Fox joined the Redskins, he leap-frogged Horatio Blades as London Fletcher’s backup. On Friday, with Fletcher sidelined with hamstring and groin injuries, Fox got the start and helped set the pace for another strong showing by the Redskins’ defense.

Fox, who had the calls radioed into his helmet and then relayed them to his teammates in the huddle, signed with the Redskins after spending the last three seasons in Pittsburgh. During the 2008 and 2009 seasons, current Redskins linebackers coach Lou Spanos held the same position in Pittsburgh, and Fox says his familiarity with the coach is a big reason why he has been able to make a smooth transition.

“It’s helped a lot. Lou’s been like a translator for me,” Fox said. “It’s just a few terminologies and stuff that’s different, but he’s really helped me interpret those and that helps me get my reads a lot.”

Following Friday’s win at Indianapolis, Fox also credited defensive lineman Barry Cofield, Stephen Bowen and Jarvis Jenkins for his own effectiveness.

“It’s a good feeling out there for a 3-4 linebacker to be able to flow and come to the ball and run downhill,” Fox said. “Those guys up front, hats off to them. They did an excellent job tonight.”
