Cowboys begin the free agency period

The Cowboys have begun the free agency period by trying to fill the 90-man roster, agreeing to terms with several undrafted free agents.

The team has reached deals with Texas Tech wide receiver Lyle Leong, Stillman College safety Michael Ricks, Georgia Tech cornerback Mario Butler, Utah State cornerback Chris Randle and Toledo center Kevin Kowalski.

Update: The team has also agreed to sign Oklahoma State kicker Dan Bailey.

As part of this process, the Cowboys can sign rookies and negotiate but not sign veteran free agents.
