Lynn's mind is going bye-bye. That's not how it works. A guy has to be cleared 100% physically before he goes back on the field whether at Lakeland, Toledo, or Det. He's not going to spend a month at Toledo getting his hitting eye back, and playing at Toledo vs Detroit has zero to do with his navicular bone's condition, it's either ready for play or it isn't and if he's playing pro baseball in Toledo there is no less stress on it there than there will be in Det. so in the opinion of the real doctors it's sufficiently healed to play, which means play anywhere. (barring some setback of course - remember this is the 2022 Tigers we're talking about.)
So the translation is.....Lynn had one of his bad days.
