San Francisco defensive lineman Tarron Jackson was taken to the hospital after collapsing on the field during 49ers training camp.

The 27-year-old went down after he was blocked on a play late in practice. He remained on the ground for several minutes before being taken off on a stretcher.

An ambulance then rushed Jackson to the hospital but coach Kyle Shanahan later revealed that he was conscious, able to communicate and feel all his extremities.

‘So hopefully, we cleared the real scary stuff, and hopefully we´ll get some good news on his neck,’ Shanahan said.

The 49ers were able to finish practice after Jackson was taken off the field.

‘It’s always hard…  especially when guys watch that,’ Shanahan said. ‘We were close to him, so we could hear him talking, we could see everything moving, so I just told the guys that, which I think eases them up a little bit for the biggest fears and asked them if they’re OK to continue to go. They all yelled “yes,” and then we finished our last period and a half.’

The 27-year-old Jackson was a sixth-round pick by Philadelphia in 2021 and has played 24 career games for the Eagles and Carolina. He signed with San Francisco in the offseason.

The 49ers activated second-year receiver Ricky Pearsall from the physically unable to perform list earlier in the day and he practiced for the first time this summer.

‘It was nice,’ Shanahan said. ‘His rep count was really low. I think he got like eight reps today, but we´ll see how he did with recovery and stuff. But I didn´t hear any complaints and good first day back.’

Pearsall had been out since injuring his hamstring during the offseason program. The Niners are counting on a big season from the 2024 first-round pick after trading away Deebo Samuel and with Brandon Aiyuk expected to miss the start of the season recovering from knee surgery.

Pearsall had a difficult rookie season, missing almost all of camp with injuries to his hamstring and shoulder and then sitting out the first half of the season after being sH๏τ in a robbery attempt in San Francisco.

Pearsall returned in Week 7 and finished the season with 31 catches for 400 yards and three touchdowns in 11 games. Pearsall had a strong finish to the season with 14 catches for 210 yards and two touchdowns in the final two games.

Cornerback Renardo Green was out after hurting his hamstring in practice on Friday. Shanahan said that he will likely miss a couple of weeks but could return the week of Aug. 11 when the Niners prepare for their second exhibition game against the Raiders.

Veteran cornerback Eli Apple agreed to a deal with San Francisco on Sunday, according to his agency Universal Sports Management. The 29-year-old Apple has played 102 games, including four with the Chargers last season.

Receiver Jacob Cowing has a similar timeline to Green after hurting his hamstring on the first day of practice last Wednesday.

Receiver Jauan Jennings left practice early with a calf injury but quarterback Brock Purdy returned to practice Sunday after missing a session on Friday for personal reasons.

‘Brock had some family stuff yesterday, all good news,’ Shanahan said. ‘I’m sure he’ll tell you guys when he talks to you guys next. But Brock was back and didn’t miss a beat and it was a good day off for him.’
