At a time when many expect the Dolphins to make a play for receiver Mike Wallace once free agency opens, they have finalized a deal to keep one of their most productive pass catchers on the team.

Per a source with knowledge of the situation, the Dolphins have agreed to terms with receiver Brian Hartline.

It’s a five-year, $30.775 million contract, with $12.5 million in fully-guaranteed money.

A fourth-round pick in 2009 from Ohio State, Hartline had a career-best 74 catches for a career-high 1,083 yards in 2012. If the Dolphins land a field-stretcher like Wallace, those number could go up.
