Tartt left Sunday's contest in the fourth quarter with an apparent shoulder injury, Matt Barrows of The Athletic reports.
Tartt was cleared for action after nursing a shoulder injury during practice this week, but it appears that his exit is related to the same issue. The 26-year-old safety recorded five tackles (three solo) prior to exiting. Antone Exum would presumably start at strong safety next week if Tartt is unable to suit up against the Chiefs.
Tartt (shoulder) was a limited participant in Thursday's practice, Nick Wagoner of ESPN.com reports.
The 49ers' starting strong safety, Tartt's Week 2 seems to be battling through a shoulder injury of undisclosed severity. It remains to be seen whether Tartt will suit up against the Lions on Sunday, but if the 25-year-old misses any time expect Antone Exum to play in his stead.
Tartt (forearm) starter Thursday's preseason opener, recording two tackles in a win over Dallas.
Tartt had his 2017 season cut short by a forearm fracture, but his presence in the starting lineup indicates good health heading towards the regular season. The 25-year-old is lined up to start at strong safety after recording 55 tackles and an interception in nine games last season.
Tartt (forearm) signed a two-year contract extension Friday, Matt Maiocco of NBC Sports Bay Area reports.
Tartt is now under contract through the 2020 season. The 2015 second-rounder emerged as the starting strong safety last year and currently seems to be the favorite to open the 2018 season in the same role. While it isn't clear where he stands in his recovery from a fractured forearm, there doesn't seem to be any concern over Tartt's availability for training camp this summer.
San Francisco head coach Kyle Shanahan said Tartt will be placed on injured reserve this week after fracturing his forearm in Sunday's loss to Arizona, Matt Barrows of The Sacramento Bee reports.
The 49ers will be without their starting safety tandem for the rest of the season after Jimmie Ward broke his forearm a week earlier in San Francisco's loss to the Eagles. Tartt, a 2015 second-round pick, who had been in the midst of a breakout season with 55 tackles and an interception in just nine games, should have a strong case for a starting role in 2018 if he makes a full recovery from surgery, as is expected.
