The team announced both signings on Wednesday, with Ben Volin of the Palm Beach Post
reporting the Vernon deal will be worth slightly more than $3 million with a signing bonus around $650,000.
The only remaining unsigned draft pick is, of course, quarterback Ryan Tannehill.
With camp starting Friday, the first-round pick's situation bears watching because he has a chance with a strong camp to earn a starting job as a rookie and every practice missed would hurt his cause.
Two days before the start of training camp, the Dolphins reduced their number of unsigned draft picks to two and then one when they agreed to terms with third-round selections Olivier Vernon and Michael Egnew.
