Kevin Williams, a five-time All-Pro with the Minnesota Vikings visited with the Patriots on Thursday, according to a source.
The 33-year-old defensive tackle is mulling whether or not to play a 12th season. He recently told Minneapolis media he may not be willing to play for a lowball contract.
He did, however, express an interest in hearing from New England. Williams told USA Today writer Tom Pelissero to look up the Patriots when Pelissero spoke to Williams about his lack of employment.
Williams will be 34 in August. His last All-Pro season was 2010. He's missed only one game the past two seasons and - at 6-5, 311-pounds remains a huge and powerful player.
The Patriots have some age and uncertainty on their interior defensive line with Tommy Kelly, Vince Wilfork, Dominique Easley and Armand Armstead all coming off injuries from 2013.
