Longtime Vikings defensive tackle Kevin Williams could be close to extending his NFL career with the New York Giants.

Williams, who turns 34 in August, flew to Newark, N.J., from Atlanta Monday afternoon. He had dinner with Giants defensive line coach Robert Nunn and other Giants defensive coaches on Monday night and will meet with head coach Tom Coughlin and members of the Giants front office on Tuesday.

"I'm not sure what's going to happen," Williams said. "I played 11 years in Minnesota. It didn't work out there, and this is my first visit with another team. I'm not sure how to feel. It's all new to me."

Williams was the Vikings' first-round draft pick in 2003. A five-time All-Pro pick and six-time Pro Bowl selection, Williams has missed only five games, including just three because of injuries. He had 60 sacks, five interceptions and seven forced fumbles with the Vikings.

But Williams never was in the plans for new Vikings coach Mike Zimmer. Williams said he accepted that as part of the business of the NFL, but also thinks he still has something left to give to the league.

"I knew eventually a team would reach out and show interest," Williams said. "But I wasn't worried about it. Either way, whether something works out [Tuesday] or doesn't work out and I retire, I'm comfortable with that. I'm not a guy who's worried about going home and leaving football behind. Football isn't everything."

Coincidentally, the Giants' need at defensive tackle stems in part from the Vikings signing New York nose tackle Linval Joseph early on in free agency. That left an opening inside next to former Packers lineman Cullen Jenkins, who signed with the Giants via free agency last year.

"I had a good visit [Monday night]," Williams said. "It's different. That's for sure. But I would like to keep playing, so we'll see how it goes [Tuesday]."

Vikings sign safety

The Vikings agreed to a one-year deal with free-agent safety Kurt Coleman. Coleman visited Winter Park on Thursday.

Coleman, 25, played his first four NFL seasons with the Philadelphia Eagles, who drafted him out of Ohio State in the seventh round in 2010. He made 29 starts for the Eagles. He lost his starting job in 2013, but he was a contributor on special teams. He has 170 tackles, seven interceptions and a pair of forced fumbles in his career.

Coleman, 5-10 and 200 pounds, will be the seventh safety on the roster, and the Vikings return a pair of starters in Harrison Smith and Jamarca Sanford.
