Armstead recorded 1.0 sack and no other statistics in Sunday's 20-17 loss to the Dolphins.
Armstead was able to make a splash play in his debut with the Jaguars, sacking Miami quarterback Tua Tagovailoa for a five-yard loss in the third quarter. The 30-year-old will look to establish himself as a force for Jacksonville on the team's interior defensive line in 2024 after spending the first nine seasons of his career with San Francisco.
