Cowboys keep DE Jason Hatcher

SAN ANTONIO -- The Dallas Cowboys continued their work along the defensive line in free agency by agreeing to a three-year deal with end Jason Hatcher, owner and general manager Jerry Jones said Monday.

According to a source, the deal is worth $6 million with a $2.5 million signing bonus.

Hatcher, a fourth-round pick by the Cowboys in 2006, received some interest from the Denver Broncos but chose to remain in Dallas.

After losing Stephen Bowen to the Washington Redskins, the Cowboys were able to re-sign Marcus Spears and Hatcher and add Kenyon Coleman in the last few days.

"We have no depth behind the top six guys," Cowboys executive vice president Stephen Jones said after Monday's practice. "We were going to make a move if it was the right situation."

Hatcher -- 6-foot-6, 311 pounds -- had 7.5 sacks in his first five seasons, including a career-best 2.5 last year.

The Cowboys are not finished in free agency.

The team is in talks with several players, including safety Abram Elam, who played the last two seasons in Cleveland. Stephen Jones said there is a possibility Dallas could sign two free-agent safeties.
