The Cowboys had their other eight draft picks signed by May 31, but with negotiations for early third-round picks across the league hitting some sticking points this year, it took some time to settle the deals for Collins and others.
While Collins, a defensive tackle, is signed, he might not be ready for the start of training camp after undergoing surgery June 1 to repair a broken right foot. He suffered the injury during the Cowboys’ organized team activities and was given a 10-to-12 week recovery period.
The Cowboys drafted Collins with the hope he could contribute immediately along the interior of their line. With the suspensions of DeMarcus Lawrence and Randy Gregory, the Cowboys could move Tyrone Crawford to defensive end depending on how Collins develops.
Collins' production slipped last season at Nebraska in part because of a switch in the team's defensive philosophies. In 2014 he had 45 tackles, 14 tackles for loss and 4.5 sacks. He had seven tackles for loss and 2.5 sacks in 2015.
