Sixth-round tackle signs, too

The Cowboys now have two of their six draft picks under contract.

Offensive tackle Sam Young, a sixth-round pick, agreed to a four-year deal on the same day the Cowboys completed negotiations with seventh-round defensive lineman Sean Lissemore. Young received a $110,000 signing bonus, which was slightly higher than Lissemore's bonus.

The 6-8, 315-pound Young was a four-year starter at Notre Dame, setting a school record with 50 starts while never missing a game. He played primarily right tackle in college, making 40 starts there and 10 on the left side. He's likely to end up at right tackle in the NFL, but he also worked some on the left side during organized team activities and minicamp.

Young might be competing with Robert Brewster, a third-round pick who missed his rookie season due to a chest injury, for a roster spot. Doug Free, Marc Colombo and Alex Barron will be the team's top three tackles.
