Coach Mike Shanahan confirmed on Friday that the Redskins had re-signed cornerback Byron Westbrook.

Due to rules regarding free agency and the new collective bargaining agreement, the second-year defensive back is not allowed to join the team until Tuesday, Shanahan said.

“He’s an exclusive free agent,” Shanahan said. “After your second year you’re exclusive, third year restricted and since he would have to sign a contract he’s just like a normal free agent even though he’s only been in the league for two years. The guideline is if you sign a new contract you can’t [practice] until next Thursday.”

Westbrook, the younger brother of former Philadelphia Eagles running back Brian Westbrook, has been a special teams stalwart for the Redskins over the past two seasons, appearing in 31 of 32 games, including one start.

Westbrook, a Dematha grad, was signed as an undrafted free agent out of Salisbury State in 2007 and spent time on the practice squad before being signed in 2009. He had 14 tackles last season

Terms of the agreement were not immediately known.
