49ers’ Tarron Jackson Collapses During Training Camp Session

It was a terrifying scene Sunday during a San Francisco 49ers training camp session after defensive lineman Tarron Jackson collapsed in the middle of an 11-on-11 drill.

Following a block, it appeared that Jackson went unconscious, leading to him lying on the ground motionless.

Jackson was tended to by medical personnel for around six minutes prior to him being removed from the field on a stretcher. Taken in an ambulance, he was transported to Stanford Hospital. (RELATED: Multiple Brawls Break Out In Falcons’ Training Camp)

Niners head coach Kyle Shanahan stated following practice that Jackson was listed in stable condition.

“Just letting you guys know he’s conscious inside. Communicating with us and can feel all his extremities. They’re taking him down to Stanford now just for further testing. Hopefully, we’ve cleared the real scary stuff, and we’ll get some good news on his neck,” said Shanahan.

ESPN’s Nick Wagoner provided more information on the situation.

“The final non-padded session for the Niners was around 80 minutes with about a 7-minute stoppage in the middle to tend to injured DE Tarron Jackson. Jackson was on the ground for about 6 minutes being tended to by trainers before he was placed on a stretcher and taken by cart to an ambulance that took him to Stanford hospital for further evaluations about 21 minutes after the play happened,” wrote Wagoner.

Drafted in the 2021 NFL Draft in the sixth round, Jackson suited up for the Carolina Panthers and Philadelphia Eagles prior to becoming a 49er in January. He’s currently a member of the team’s practice squad.
