OXNARD, Calif. -- Three more draft picks signed with the Dallas Cowboys on Thursday, leaving only veteran receiver Terry Glenn and the team's two first-round picks unsigned as they reported to California for training camp.

Glenn has refused to sign an injury waiver that would reduce his salary from $1.74 million to $500,000 if he hurt his right knee again and was unable to play. The 34-year-old receiver wasn't scheduled to be on the team's charter flight from Texas on Thursday.

The Cowboys also haven't come to terms with running back Felix Jones from Arkansas or cornerback Mike Jenkins from South Florida.

Second-round pick Martellus Bennett from Texas A&M was among those who signed Thursday. Also signing were fourth-round pick Tashard Choice, a running back from Georgia Tech, and sixth-round pick Erik Walden from Middle Tennessee State.

Cornerback Orlando Scandrick signed a four-year contract Wednesday, making the fifth-round pick from Boise State the first of the Cowboys' draft selections to sign.

Glenn didn't play until the regular season finale last season, when he got a $5 million roster bonus, after having two operations on this right knee.
