Tannehill’s agent has come out and said that Ryan Tannehill has a broken foot. http://espn.go.com/nfl/draft2012/story/_/id/7454270/2012-nfl-draft-qb-prospect-ryan-tannehill-broken-foot-agent-says
While historically injured players (Bradford, Clausen, etc.) can still have high draft statuses this could affect Tannehill more since he had such a short QB career. I think this kills any chance of him being a first rounder, and could slide him behind Foles and possibly Weeden in the 2nd round.
