The underlined part happened after his concussion when his play fell off a cliff, which happened in the first half of their 10th game, so he was healthy and good for a little over half the year. Here are some more examples:

It feels obvious even if it's uncertain, but a Pro Football Focus analyst has an obvious prediction on Jeff Okudah's fifth-year option.

"After two injury-riddled seasons to start his career, the 2022 season was a critical one for Detroit Lions cornerback
Jeff Okudah. And for a big portion of it, he played quite well. Then a concussion
cost him the Thanksgiving Day game on a short week, and it was all downhill from there."
The Lions will receive a 2023 fifth-round pick in exchange for Okudah.

"PFR ranked him among the top 24-33 cornerbacks last season in the site’s Approximate Value metric. Others within the group included Carlton Davis,
Stephon Gilmore and
Jaycee Horn. Okudah ranked 40th among cornerbacks in 2022 in Sports Info Solutions’ Total Points Saved metric. All of these metrs basically point to the Falcons acquiring a viable starting cornerback and a seemingly ascending player. —

"Drafted No. 3 overall in 2020, Okudah battled injuries in each of his first two seasons, including a torn Achilles in the first game of 2021. He made seven starts in 10 games across the two campaigns. As such, Okudah, 24, entered 2022 searching to prove why he was so highly thought of during the pre-draft process - and largely did."
There are plenty more out there that echo the same sentiment: Overall, he was playing very well until his concussion. Detroit had no intention of picking up his option so I guess getting something is better than getting nothing, but given what they have in the defensive backfield after this coming season, it wouldn't have been the worst thing to keep him on and see if he could build off last year.
