The 49ers have beefed up their defensive line in the wake of Arik Armstead‘s injury. Defensive tackles Tony McDaniel and Leger Douzable have been signed, as Adam Caplan of SiriusXM reports (Twitter links).

McDaniel, 32, has experience in a system similar to SF’s thanks to his time in Seattle. Defensive coordinator Robert Saleh was even on staff with the Seahawks during one of his seasons with the team. In that year, McDaniel started a career-high 15 games and recorded 53 tackles (a career mark) plus two sacks.
Douzable missed the Niners’ initial cut, but he is back with the team here in October. The 31-year-old appeared in every game for the Bills last season (including five starts) and had 43 total tackles and 1.5 sacks.
