Sorry to beleaguer this but a muscle strain and a muscle tear are not the same thing:
https://www.medicinenet.com/is_a_muscle_strain_the_same_as_a_muscle_tear/article.htmA muscle strain is an injury that occurs when a muscle or a tendon is overstretched. A muscle tear is when a muscle or a tendon is overstretched and it tears. A muscle strain is not the same thing as a muscle tear.
Although a muscle strain is different from a muscle tear, many people get these injuries confused. A strain is an injury that involves a muscle or tendon being overstretched. Your doctor may also call the injury a pulled tendon or muscle pull. (A tendon is the cord of tissue that attaches a muscle to a bone.)
Sometimes the injury is more severe, and one, a few, or all of the muscle fibers get torn. In this case, you have a muscle tear.
My understanding is that the injury Porzingis suffered was reported to be a "muscle strain". I believe that if this was a muscle tear, we would not even be talking about whether or not he would return for the playoffs at all, he would be done for the season.
I don't recall if they reported whether this was a Grade 1 (2-3 weeks recovery) or a Grade 2 (4-6 weeks recovery). A Grade 3 strain or a tear is generally season ending. The injury was on Apr 29 I believe so Monday will be 3 weeks.
I don't know the state or progress of his recovery/re-strengthening or the severity of the original injury. I don't advocate playing him until the Doctors say he has a clean MRI and he says it feels good but if he has a clean MRI and he says it feels good, I see no reason to give him extra rest. It does not appear that they are at that point. It appears they are only just starting the strengthening and getting back in shape.
I would not push it if you don't have to push it. But there could be a point where you have to push it. For example if we go down in the NYK/IND series. Or we get down in the finals. Where giving him another week may mean the end of the season. Based on what is being reported, it seem like there is a soft goal to get him back at some point in the next round. That would be ideal to have him truly 100% for the finals.
