Don't know how many of you philistines watch tennis, but there's a French woman playing Coco Gauff right now in the semis. She tore her ACL one week before last year's French Open, so the one year anniversary of the tear would have been two weeks ago. From what I can find, her first tournament back started on April 12th of this year. She won her first match and lost the second. Not sure when she started practicing, but it's reasonable to assume she was all the way back by the end of March. So a reasonable estimate is that she was back roughly 10 months after the injury. Her career earnings before the French Open were under $200k, so it's pretty likely that she didn't have the same rehab resources that Quaintance has.
If he's on the same timeline, that would put him back just before Christmas. Just food for thought.
