The Dallas Cowboys have announced that they have re-signed defensive end Anthony Spencer.

The 30-year-old played just one game for the club in the 2013 season due to a knee injury, but has penned a one-year contract after being allowed to test the free-agent market.

"Happy to announce that Anthony Spencer has re-signed with the Dallas Cowboys on a one-year deal," Spencer's agent Jordan Woy said on Twitter.

Spencer has been with the Cowboys since the 2007 season and was voted to the Pro Bowl in 2012.
