Dolphins' Louis Delmas tears ACL
Monday December 8th, 2014

Miami Dolphins safety Louis Delmas tore the anterior cruciate ligament (ACL) in his right knee during Sunday's loss to the Baltimore Ravens and will be placed on injured reserve, coach Joe Philbin announced on Monday.

Delmas, 27, was injured during the fourth quarter while trying to tackle running back Justin Forsett.

Delmas is in his first season with the Dolphins and has 61 combined tackles, one interception and one sack this season. He spent the first five seasons of his career with the Detroit Lions after being a second-round pick in 2009. 

He is the latest in a string of injuries to Miami's secondary. Starting cornerback Cortland Finnegan has missed the last four games with an ankle injury and Jamar Taylor has missed the last two games with a shoulder injury.

The Dolphins are No. 6 in yards allowed and No. 7 in scoring defense this season. The passing defense has been strong and has allowed the third fewest yards in the league.

The Dolphins are 7-6 and one game behind the San Diego Chargers for the final playoff spot in the AFC. They play at the New England Patriots on Sunday at 1 p.m. ET.
