He's the second Patriot rookie to sign, joining sixth-round pick Ted Larsen. Bears fourth-rounder Corey Wootton, 109th overall (19 picks back of Price) had been the highest signed pick in the league.
Price was impressive during minicamp, but is considered a bit of a raw prospect having come from Frank Solich's option offense in Athens. And despite having signed, Price is not permitted to report to Foxborugh until after June 11, the final day of finals at OU.
That means we probably won't see him again until the full-squad minicamp June 15-17.
ESPN's Adam Schefter was first to report the news.
