Jaquiski Tartt returned to practice Friday, but it was decided afterward the 49ers safety won’t play Sunday against the Seattle Seahawks, marking the sixth game he’ll miss this season because of an ailing shoulder.
“He was out there but didn’t do much,” coach Kyle Shanahan said.
Tartt hasn’t played since aggravating the injury while making a tackle on the second-half kickoff during the last game between the teams Dec. 2. He suffered the injury during the season-opening loss to the Vikings, and it has remained problematic.
Tartt’s absence makes it likely rookie sixth-round pick Marcell Harris will make his third straight start on the heels of a promising performance in last Sunday’s 20-14 victory over the Denver Broncos.
