Here's what the wiki has on Ja'Quinden Jackson's injury:
During preseason Week 2 (Aug 22, 2026) against the Patriots, Jackson was taken off the field in an ambulance after a collision on the opening kickoff. It was a scary scene — he was involved in a tackle on special teams and suffered what's being described as a possible head/neck injury.
The good news: early reports confirmed he showed movement and strength in all extremities on the sideline before being taken to a local hospital for observation (from the Ja'Quinden Jackson page). That said, the extent of the injury is still unclear — an MRI was pending, and his availability for the 2026 season remains in doubt.
Unfortunately, the wiki hasn't been updated with any follow-up news since the initial report, so the final diagnosis and timeline are still unknown. I wasn't able to find expert takes specifically addressing him either.
