James Walker of ESPN reports that the Dolphins are signing S T.J. McDonald to a four-year, $24 million extension that includes $10 million in guaranteed money.
McDonald, 26, is a former third-round pick of the Rams back in 2013. He played out the final year of his four-year, $2.926 million rookie contract before signing a one-year, $1.34 million contract with the Dolphins this offseason.
McDonald will, however, have to serve an eight-game suspension to open the year.
In 2016, McDonald appeared in all 16 games for the Rams and recorded 64 tackles, one sack, two interceptions and six pass defenses.
