The Miami Dolphins are expected to pick up the fifth-year option on Miami Dolphins center Mike Pouncey, who was the 15th overall pick in the 2011 NFL draft.

According to a league source, picking up Pouncey's fifth-year option commits a little over $7.4 million to the 2014 Pro Bowl selection because he wasn't one of the top 10 picks in the 2011 draft, which was the first draft class subjected to the new CBA salary structure for rookies.

The deadline to pick up the fifth-year option, which is available for all first-round picks from the 2011 draft and on, is Saturday. The option on Pouncey, and all others who receive it by the deadline, is guaranteed for injuries-only before the first day the 2015 regular season, which is when the contract becomes fully guaranteed.

The CBA stipulates the fifth-year options pay the top 10 picks the average of the top 10 players at their respective position. That number for quarterbacks is $14.6 million this season, and that price will likely rise next season when the Dolphins must decide if they'll pick up Ryan Tannehill's fifth-year option as the eighth overall pick in the 2012 draft.

The fifth-year option for defensive ends picked in the top 10 is $10.6 million this season, and that figure will likely grow in 2017 when Miami must decide whether to opt in on Dion Jordan's fifth-year option as the third overall pick in the 2013 draft.

Teams can sign any player past the third year on their rookie deal to a multi-year extension, but in most cases it doesn't benefit them to do so when it comes to the fifth-year option players, especially if they weren't a top 10 pick like Pouncey. Players drafted outside of the top 10 receive the average salary of players three through 26 at their position.

Pouncey has started all 46 games he's played for the Dolphins, and was voted to the team's leadership council last season. However, the former University of Florida standout was one of three individuals incriminated in the NFL's independent investigation on the Dolphins' bullying scandal, which motivated former offensive lineman Jonathan Martin to leave the team claiming he was harassed.
