The good news ... he eventually got back on the mat and returned to form -- securing 3rd place at the NJSIAA/Rothman Orthopaedics District 29 tournament in New Jersey over the weekend in the 120-pound division.
After the district tourney, Andrew told NJ.com, "I tried to block everything out and just wrestle."
One of the cooler parts of the story ... Johnson's little bro, Nate -- a freshman -- finished second in the tourney and will also advance to this week's regionals.
"We're both moving on, so we're ready," Andrew said.
Their mom, Rosa Johnson, also weighed in -- saying, "Our family has just rallied around them and kept them focused."
"We've tried to protect them. They've worked really hard for this and wanted to keep them focused."
