“He’s a playmaker on our defense and a big part of what we do,” 49ers linebacker Fred Warner said. “Having him back is exciting.”
Greenlaw underwent surgery to repair the injury the following week.
Tartt missed three games with a bone bruise in his knee. Rookie Talanoa Hufanga started the past three games and played well in Tartt’s absence.
Coach Kyle Shanahan said Tartt will not automatically get his starting job back when he is cleared to play.
