On Day 3 of official free agency, the Dolphins are adding multiple linebacker pieces. They have agreed to terms with Duke Riley and Brennan Scarlett, according to NJ.com’s Mike Kaye and the Houston Chronicle’s Aaron Wilson.

Both players finished last season on IR. While each could offer depth, both Riley and Scarlett have starting experience. Both spent part of the 2020 season operating as starters — for the Eagles and Texans, respectively. Riley agreed to terms on a one-year pact, per Kaye.

A five-year Texans contributor, Scarlett started 22 games. The former UDFA worked as more of a pass-rusher in Houston, playing on the outside in the Texans’ 3-4 scheme, but also offers some versatility. Scarlett started 10 games in 2019, registering 51 tackles and recording 3.5 sacks. He suffered a season-ending broken forearm midway through last season.

The Eagles signed Riley a year ago and used him as a starter in eight games. Despite missing three games, Riley played on 55% of Philadelphia’s defensive snaps. A Falcons starter in 2017 and ’18, Riley recorded 55 tackles last season and was a special teams captain in Philly.

Scarlett makes for the second ex-Texans linebacker the Dolphins have acquired this week. They traded for Benardrick McKinney a few days ago. Miami also brought back linebacker Vince Biegel this week.
