OXNARD, Calif. -- With injuries keeping five defensive linemen out of practices, the Dallas Cowboys agreed to deals with end Ken Boatright and Adewale Ojomo.

Rookie defensive end DeMarcus Lawrence had surgery on a broken foot on Thursday and is expected to miss eight to 10 weeks. Defensive tackle Terrell McClain has been battling a sprained ankle and Ben Bass suffered a hamstring strain on Thursday. Anthony Spencer is on the physically unable to perform list and Amobi Okoye is on the non-football injury list. Their absences have put a strain on the remaining defensive linemen.

To make room on the roster, wide receiver L'Damian Washington and guard Darius Morris will be waived.

Boatright, who is 6-foot-3, 254 pounds, spent time with the Seattle Seahawks last season after signing as an undrafted free agent. He was cut in June. Boatright’s agent, Brett Tessler, tweeted the agreement.

Ojomo was cut by the Tennessee Titans following an arrest for soliciting a prostitute. He has spent time with the New York Giants, Seahawks and Buffalo Bills since 2012. He has played in one game in his career.

In addition to Boatright and Ojomo, the Cowboys also worked out Cory Henry, who went to rookie minicamp with the Houston Texans on a tryout basis. He had 32 career sacks at Florida Atlantic.
