Former Vol Willingham signs with Cowboys

The Dallas Cowboys shored up their injury-plagued rookie class by adding undrafted cornerbacks DeAngelo Willingham and Jeremy Haynes.

The Cowboys also cut receiver Julian Hawkins on Tuesday and placed linebacker Brandon Williams on season-ending injured reserve with a torn knee ligament.

Lineman Robert Brewster was moved off the active roster because of a right shoulder injury.

Willingham signed with Tampa Bay out of Tennessee and was released after the Buccaneers' third preseason game. Haynes joined the Tennessee Titans out of McNeese State but was released after playing in the first preseason game.

The Cowboys finish the preseason Friday night at Minnesota and must cut their 75-player roster to 53 by Saturday.
