MONTREAL - The Montreal Alouettes bolstered their defensive line Wednesday with the signing of Canadian defensive tackle Vaughn Martin to a two-year deal.

The six-foot-four, 300-pound Martin spent seven seasons in the NFL after being drafted in the fourth round, No. 113 overall, in 2009 by the San Diego Chargers. He spent four seasons in San Diego before joining the Miami Dolphins in 2013 and also spent time with the Detroit Lions and Kansas City Chiefs.

Martin, 29, appeared in 51 career NFL games, registering 79 tackles, three sacks and a forced fumble. He played collegiately at the University of Western Ontario.

"This has been a long and calculated process to finally get Vaughn to Montreal," Montreal head coach/GM Jim Popp said in a statement. "Talks have gone on over the last couple of years, up to Vaughn making a visit to Montreal and taking a medical.

"Vaughn has a chance to come in and offer us a force inside, partnered with Alan-Michael Cash, that could cause teams a lot of problems. We obviously are excited about the possibilities and welcome him to the Alouettes."
