San Francisco 49ers safety Jaquiski Tartt is day-to-day with a shoulder stinger, head coach Kyle Shanahan told reporters on Monday. His availability against the Kansas City Chiefs this weekend is uncertain.
Tartt left Sunday's game on the first snap of the Lions' final drive. He went into the game with the shoulder injury and re-injured it. Tartt had five combined tackles against Detroit before exiting and had six tackles and a pass defensed against the Minnesota Vikings a week earlier.
The 49ers made Tartt a second-round draft pick out of Samford in 2015. He signed a two-year contract extension in April. The new deal will keep Tartt in San Francisco through the 2020 season.
Tartt's 2017 season was cut short by a broken forearm. He has registered 192 combined tackles, 3.5 sacks, 10 passes defensed, two interceptions, and a forced fumble in three-plus career seasons.
