Patterson, the longtime Philadelphia Eagle, was released in late February. The 29-year-old former first-round draft pick visited with the Detroit Lions shortly after, but no deal was reached.
Patterson's visit included a physical, according to reports, as Patterson's seizure during training camp in 2011 nearly ended his career. In January 2012, he underwent surgery to remove an arteriovenous malformation from his brain.
Another former Philly defensive lineman, Cullen Jenkins, signed with the Giants earlier in the off-season after the team released Chris Canty in February. Another defensive tackle, Rocky Bernard, is not expected to return either.
Patterson played 99 games, all with Philadelphia, racking up 16.5 sacks. He has played in 15 or 16 games per year in seven of his eight seasons, with the exclusion of last year.
Potentially, Patterson would be a veteran to fill the team's need at defensive tackle. Aside from the newly signed Jenkins, the team is young at the position with Linval Joseph, Marvin Austin and Markus Kuhn rounding out the depth chart.
Along with Patterson, free-agent quarterback Pat White and running back Tim Hightower will visit the facility today.
