The 11-year-old, who had to be put in a medically induced coma, was stabbed in the neck on the field in the Topsail area of Conception Bay South, in an incident that attracted national attention.
Nicholas Layman, 19, is undergoing a month-long psychiatric assessment, and has been charged with attempted murder.
The boy cannot be identified because of a court-ordered publication ban.
Calvin Randell, president of the Conception Bay South Soccer Association, spoke to CBC News on Thursday with the permission of the boy's mother.
"She calls him her miracle," said Randell, adding that the boy is eager to get well enough to join his soccer teammates again.
"The recovery is coming along very well, both physically and emotionally," he said.
"He can't wait to get back to kick at a ball."
No motive has been established in the case, with sources familiar with the police investigation telling CBC that the attack appears to have been random, and that mental-health issues are paramount in the case.
The Sept. 25 attack happened while about 100 children were taking part in drills.
