The Patriots have signed second round picks Ras-I Dowling and Shane Vereen, as well as rookie free agent Christian Cox. They also released first-year quarterback Jonathan Crompton.
In addition, Mike Reiss of ESPN Boston reports the team has brought in free-agent linebacker Matt Roth, formerly of the Browns and who has also played with the Dolphins, for a workout.
Dowling, a 23-year-old defensive back from the University of Virginia, was selected 33rd overall. He recorded 160 tackles in 40 games during his college career and was named team captain as a senior.
Vereen was picked 56th overall. A 22-year-old running back from the University of California, Berkley, he rushed for a total of 2,834 yards and 29 touchdowns in his college years. He also made 74 receptions for 674 yards and six touchdowns, returned 24 kickoffs for 551 yards, and returned two punts for ten yards. His 4,069 total yards rank him fifth all-time at his school.
Cox, 25, is a defensive end who started all 13 games at the University of Utah in 2010, recording 53 tackles and four sacks.
Crompton, originally a fifth round pick by San Diego in 2010, was signed to the Patriots' practice squad on November 3 after being waived by the Chargers.
