The Dolphins reached agreements Wednesday with two of their unsigned draft picks.

Defensive end Olivier Vernon signed a four-year contract worth $2.848 million with a signing bonus of $638,080. The Dolphins also signed tight end Michael Egnew later in the day to another four-year contract. The terms are undisclosed.

With Vernon and Egnew secured, the Dolphins’ only remaining unsigned draft pick is first-round quarterback Ryan Tannehill. Once signed, the eighth overall pick is expected to compete with offseason signee David Garrard and incumbent Matt Moore for the starting quarterback spot.

Vernon (6-3, 260 pounds), a former University of Miami standout and graduate of Hialeah American High, is expected to compete for a starting job at defensive end opposite Cameron Wake. The Dolphins drafted Vernon in the third round (72nd pick), making him the first player they drafted from UM since 2004 (Vernon Carey).

The Dolphins, who were impressed with Vernon’s physical abilities during May’s rookie camp, are looking for Vernon to fill the role of a pass-rushing specialist similar to Jason Taylor’s role last season.

Egnew, a third-round pick from Missouri, caught 147 passes for 1,332 yards and eight touchdowns during his college career. Egnew should have a good chance at competing for playing time in an offensive system that is expected to employ multiple tight end sets.

• Even though most of the training camp practices, including Friday’s opener, will begin at 8 a.m., the team said that fans will not be permitted to begin watching until 8:40 a.m. The first 40 minutes will be held inside the team’s practice bubble.
