The San Francisco 49ers welcomed back offensive guard Jonathan Cooper on Tuesday, activating him off the Physically Unable to Perform List. He only worked in individual drills, sitting out team drills as he continues working back into football shape.
On Tuesday, Mike Person and Erik Magnuson split first team right guard duties. Joshua Garnett had been splitting work with Person, but he banged knees with another player over the weekend, and is letting the knee recover. Garnett received an anti-inflammatory shot in his knee, according to Mike Garafolo.
