Although Chandler is favoring the leg, his limp is not pronounced, so they knocked him out to do x-rays and manipulate his leg.
There is no laxity in the right knee-so if there is a cruciate tear, it is tiny.
They also said xrays showed nothing abnormal.
(Plus his hips look good (informally); Yeah!)
Diagnosis was either a soft tissue injury or panosteitis, which I guess translates into he did something to a muscle or has growing pains.
The bottom line is that he is supposed to rest for another month, although he can go on leash walks and do other easy exercises like swimming. No bouncing or running allowed.
