Louis Delmas appears to be done playing in 2014.
The Dolphins are awaiting MRI test confirmation, but the belief is Delmas tore the ACL in his right knee on Sunday during the 28-13 loss to the Baltimore Ravens.
[Updated 12:30 on Monday: The MRI this morning confirmed Delmas tore his ACL. He is being placed on injured reserve. He is done for the remainder of the year.]
Delmas, 27 years old and in his sixth season, had started 12 of 13 games for the Dolphins and played in all of them and was not only a cog to the team's pass defense but to the run defense as well.
Delmas the past two weeks against Denver and the New York Jets had collected 18 tackles as both those opponents had tried to run against the Dolphins. Delmas, a tough-minded and physical strong safety, often was used to overload the tackle box to augment the run defense.
Losing Delmas will mean the Dolphins will probably use Jimmy Wilson at strong safety along free safety Reshad Jones.
[Update: The injury to Delmas is not problematic beyond the ACL. No other ligaments were involved so a source tells me he should be ready to go for the start of training camp in 2015. Delmas was on a one-year contract with the Dolphins so it is uncertain what team's training camp he'll be in next year.]
Delmas went down in the second half against the Ravens while trying to make a play on a running play. Although there was no contact on his knee, he seemed to plant awkwardly and went down in a heap.
Delmas left the game on a cart after multiple teammates had come to his side to wish him well.
Delmas was in his first season with the Dolphins. If/when the MRI confirmation comes, Delmas will become the third significant free agent addition from the offseason to go down with a season-ending knee injury, joining Branden Albert and Knowshon Moreno.
