DAVIE, Fla. -- The Miami Dolphins have placed starting safety Louis Delmas on season-ending injured reserve, coach Joe Philbin announced Monday.

Delmas injured his knee in the second half of Sunday's 28-13 loss to the Baltimore Ravens.

"It's a big challenge," Dolphins defensive coordinator Kevin Coyle said. "Louis has had a very good season. He's an emotional leader on the team, as well. So we're going to miss him a lot."

Delmas, who signed a one-year contract in the offseason, was a consistent presence in Miami's secondary. He recorded 61 tackles, one interception and one sack in 13 starts.

Delmas adds to the long list of injuries in Miami's secondary. The team lost backup cornerback Will Davis (knee) for the season and Jamar Taylor (shoulder) and Cortland Finnegan (ankle) are trying to work their way back from ailments.

The Dolphins (7-6) will travel to play the New England Patriots (10-3) on Sunday.
