Defensive lineman Arik Armstead is signing a 3-year, $51 million contract with the Jacksonville Jaguars, a source told ESPN's Adam Schefter.
The San Francisco 49ers released Armstead on Wednesday after he and the team failed to work out a restructured contract. He is coming off a season in which he played in 12 games with 27 tackles and five sacks for the NFC champion 49ers.
He also is coming off a torn meniscus in his right knee, an injury he suffered in a Dec. 3 win at the Philadelphia Eagles. Armstead finished that game after suffering the injury on the second play, but he did not play again until the Jan.
20 NFC divisional round win against the visiting Green Bay Packers. Armstead, 30, appeared in all three of San Francisco's playoff games, posting 11 tackles, a sack, 7 quarterback pressures and a fumble recovery on 148 snaps.
