Steelers sign first-rounder David DeCastro

Forced to miss most of the offseason workouts, Steelers guard David DeCastro won't be a late arrival for training camp.

DeCastro, Pittsburgh's first-round pick, became the last player of this year's Steelers draft class to reach a deal, agreeing to a four-year deal, according to the Post-Gazette.

Expected to be the Steelers' starting right guard this season, DeCastro couldn't attend a majority of the team's spring workouts because the academic calendar year at Stanford wasn't over. He won't miss any time this summer after signing his $7.8 million deal.

DeCastro's signing was expected to happen this week and it likely sped up after the Detroit Lions signed offensive tackle Riley Reiff earlier today. Reiff was the 23rd overall pick, one spot ahead of DeCastro.

The only unsigned player left on the Steelers is wide receiver Mike Wallace, who is a restricted free agent. This also means there's only three AFC North draft picks who are unsigned: Browns running back Trent Richardson (first round), Browns quarterback Brandon Weeden (first round) and Bengals defensive tackle Brandon Thompson (third round).
