The San Francisco 49ers were interested in free agent defensive lineman Richard Seymour, multiple media outlets reported Sunday.
Seymour and the 49ers could not agree to terms in September, according to CBSSports.com. The Detroit Lions and Atlanta Falcons are also reportedly interested in the 34-year-old.
The New England Patriots initially expressed interest in Seymour after losing Vince Wilfork to a season-ending right Achilles tendon injury last week but decided not to sign him.
The 49ers pursued Seymour after pass-rusher Aldon Smith went on indefinite leave to deal with personal issues. However, the 49ers need help on the inside with nose tackle Ian Williams sustaining a season-ending ankle fracture Sept. 15. Glenn Dorsey is occupying that spot with Williams out.
Seymour, a former Patriot and Oakland Raider, had his contract voided by the Raiders in February but he accounts for almost $14 million on the team's salary cap this season.
The 49ers are also interested in quarterback Josh Freeman, who was released by the Tampa Bay Buccaneers last week. He is expected to choose a team by Monday. NFL.com reported Freeman will likely not choose San Francisco because he wants to start and the 49ers are set with Colin Kaepernick. They also have Colt McCoy and John Skelton on the roster.
Also, ESPN reported that 49ers defensive back Donte Whitner's paperwork to legally change his last name to "Hitner" was delayed because of the federal government shutdown.
