SANTA CLARA -- The 49ers today signed first-round pick Arik Armstead to a four-year deal, meaning all 10 of their picks are under conract on the eve of the team’s rookie minicamp.
The other nine contracts were completed early in the week and those players have been on hand since Monday. Because the University of Oregon’s class schedule will run through May, NFL rules prohibit Armstead (Pleasant Grove High) from joining team practices in full until early June.
Still, Armstead is allowed to take part in the rookie minicamp. He arrived on Friday for a physical and is expected to be on the defensive line -- perhaps lining up as the team’s left defensive end -- when the minicamp begins.
Earlier this month Armstead said the 49ers and Ducks use their linemen in similar ways and that he watched game film of 49ers defensive end like Justin Smith and Ray McDonald while at Oregon.

"They have their own little wrinkle to it," he said of the 49ers’ system. "But the base of it is similar and similar play calling. They just call it a little different. I think I’ll be able to familiarize myself and get used to it quick and make that smooth transition."
