Although the first two picks in the NFL Draft -- Andrew Luck and Robert Griffin III -- have signed contracts, it may take a little longer for the Miami Dolphins to sign quarterback Ryan Tannehill.

The Dolphins are holding firm in terms of the so-called offset language in Tannehill's contract, ProFootballTalk reported Thursday.

Offset language protects teams financially if players are released during their initial four-year contracts, which typically are fully guaranteed. The inclusion of offset language reduces the team's financial obligation if that player signs with another team.

The Colts and Redskins did not insist on offset language when they signed Luck and Griffin, respectively.

According to the report, Dawn Aponte, the Miami Dolphins vice president of administration, is insisting on offset language in Tannehill's contract.

Tannehill was the No. 8 overall pick in the draft.
