31 Isaiah Johnson CB

Johnson underwent minor back surgery Tuesday according to his personal Twitter account.

Johnson noted that the procedure was minor and he will be back in plenty of time for the 2020 season. Look for more updates on his status when the Raiders return for offseason workouts.

Johnson (concussion) was activated off injured reserve Monday, Jerry McDonald of the Oakland Tribune reports.

Johnson was designated to return and started practicing Oct. 14, so Monday was the final day of the 21-day window to activate him. The rookie fourth-round pick may start out in a depth role, but he could easily carve out a sizable role in Oakland's secondary given its porous pass defense.

Johnson (concussion) is practicing Monday, Scott Bair of NBC Sports Bay Area reports.

The Raiders have a 21-day practice window to decide whether to officially activate Johnson or place him on season-ending injured reserve, per Blair. The rookie fourth-round pick appears to be progressing well in his recovery, and he would likely play a depth or rotational role in Oakland's secondary if activated to the roster.

Coach Jon Gruden plans to have Johnson (concussion) return to practice Monday, Scott Bair of NBC Sports Bay Area reports.

Johnson landed on injured reserve in early September due to the concussion, and Monday would be the earliest he's allowed to resume practicing. The 23-year-old appears on track to return when first eligible after spending the first eight games on the shelf.

Johnson (concussion) announced via his Twitter profile that he was placed on injured reserve Monday and that he's also dealing with a fracture on the right side of his face.

Johnson originally suffered the injuries Aug. 11. The 23-year-old won't be eligible to return until Week 9 if he's able to recover from his injuries by then. For now, it seems that Keisean Nixon will shoulder the extra reps in Johnson's absence.

Coach Jon Gruden said Sunday that Johnson is dealing with a facial injury, and his status for Week 1 is unclear, Scott Bair of NBC Sports Bay Area reports.

The injury is said to have something to do with his vision and likely stems from a concussion he suffered in the first game of the preseason. It's unclear if Johnson has cleared the concussion protocol, but he'll have to receive full clearance before returning to the field. If the Houston product can't go for Week 1, Nick Nelson could see an increased role in the defense.

Johnson left Saturday's preseason win over the Rams early after he suffered a concussion and didn't return, Paul Gutierrez of ESPN.com reports.

It's unclear how the Houston product picked up the injury, but it's certainly a negative that he was diagnosed with a concussion. Johnson will now enter the leagues mandated concussion protocol and will have to gain medical clearance before returning to the field. The 2019 fourth-round pick will now miss out on valuable reps until he's fully healthy.

The Raiders selected Johnson in the fourth round of the 2019 NFL Draft, 129th overall.

A converted wide receiver, Johnson brings length and athleticism to the cornerback position out of Houston. Johnson checks in at 6-foot-2 and 208 pounds with legit 4.40 speed and can still reach another level if developed properly. He may be raw initially for the Raiders but in time he can challenge for a starting role opposite Gareon Conley.
