Arizona Cardinals sign rookies Shaq Riddick and J.J. Nelson

The Arizona Cardinals signed Shaq Riddick and J.J. Nelson to four-year contracts Tuesday.

Both players were chosen in the fifth round of the 2015 NFL Draft, with Riddick being taken 158th overall and Nelson one spot later.

Riddick, who played for West Virginia last year, was a defensive end in college but will be converted to an outside linebacker in the NFL. Last season, as a senior, he tallied 27 tackles, seven sacks and 11 tackles for loss.

Nelson, a receiver, was the fastest player in the NFL Draft after running the 40-yard dash at 4.28 seconds at the NFL Scouting Combine. A dynamic kick returner, he was a Walter Camp first-team All-American as a senior after leading the country with four kickoff returns for touchdowns as well as a 38.3 yards-per-return average.
