The Giants added their second ex-Philadelphia Eagle to the middle of their defensive line on Wednesday when they agreed to terms with free-agent Mike Patterson on a one-year deal, an NFL source confirmed.

Patterson, a 29-year-old defensive tackle, joins former Eagles defensive tackle Cullen Jenkins on the Giants. They were both cut on the same day in late February in a salary cap purge. Jenkins very quickly landed a three-year, $8 million deal with the Giants, while Patterson had to wait his turn.

His term came on Wednesday after the Giants brought him in and gave him a physical, which a source said was a key part of the evaluation process. Patterson’s career nearly ended in the summer of 2011 when he suffered a seizure during training camp. He eventually needed surgery to remove an arteriovenous malformation from his brain in January, 2012.

Patterson played in 99 games for the Eagles during his eight seasons and had 16 ½ sacks. He will likely be a depth player in the rotation behind presumed starters Jenkins and Linval Joseph. The giants also have veteran Shaun Rogers, the promising Marvin Austin and the recovering Markus Kuhn (torn ACL) at that position.

The Giants released defensive tackle Chris Canty in February, and defensive tackle Rocky Bernard is an unrestricted free agent who is not expected to be re-signed.
