The financial end of Tannehill's deal has already been agreed to. He'll receive a four-year contract that's worth about $12.6 million, and features a fifth-year option that is held by the team. And all of Tannehill's money will be guaranteed, which is standard for first-round deals under the new CBA.
The holdup for Tannehill, who was selected eighth overall after starting 19 games at quarterback for Texas A&M, is offset language, which involves how much of his salary Tannehill would receive from the Dolphins if Miami released him, or placed him on injured reserve.
Missing practice time could set Tannehill back considering the rookie is involved in a three quarterback competition to determine who will serve as the season-opening starter against Houston on Sept. 9. He's competing with veteran quarterback David Garrard and incumbent starter Matt Moore for the spot.
Defensive end Olivier Vernon, a third-round pick from the University of Miami, and tight end Michael Egnew, also a third-round pick, signed standard four-year contracts on Wednesday.
Vernon, who left UM as a junior, will receiver a $638,080 signing bonus, and will net just over a million dollars in his first NFL season. The entire four-year deal is worth $2,848,080.
Egnew's deal is worth $2,776,456 and includes a signing bonus of $588,956.
Vernon, who had 82 tackles, nine sacks and one interception in the 30 games he played as a Hurricane, is expected to fill the role Jason Taylor held last season as Miami's pass rushing specialist. That means he'll likely be paired with Cameron Wake as a rush end on obvious passing downs.
It is also possible he could push Jared Odrick for the starting spot opposite Wake. But he'd need a sensational training camp to unseat Odrick, the Dolphins' 2010 first-round pick, who had 22 tackles, six sacks and one interception as a part-time starter last season.
Egnew, who caught 147 passes for 1,332 yards and scored eight touchdowns during his career at Missouri, will compete with Anthony Fasano and Charles Clay for playing time in an offense that will use multiple tight end sets regularly.
With Egnew and Vernon's deals done the Dolphins can turn their attention to signing Tannehill, the Dolphins' first-round pick.
Players report to training camp on Thursday and practices begin on Friday at 8 a.m.
