"We did have an incident, but Mr. DeSantis hasn't even talked to Chazzy yet," Bowers said. Robert DeSantis is the school's principal.
Students and one of Thomas' former teammates spoke out on Twitter about Thomas' role in the incident.
"Apparently Chazz stopped the kid that stabbed the other kid. Leggo Chaz," Morgantown High student Adam Shaw tweeted.
"True tweet," Thomas replied via Twitter.
Former Morgantown wide receiver Blaine Stewart, son of the late West Virginia University football coach Bill Stewart, applauded his former teammate's actions on Twitter.
"Every good thing Chazzy Thomas has ever done on the field is nothing compared to today. Damn I'm proud to call him a friend," Stewart tweeted.
The school was placed on lockdown while police and paramedics worked at the scene. The 14-year-old boy was taken into custody. A folding pocketknife with a 2-inch blade believed to have been used in the stabbing was taken as evidence.
He was charged with unlawful assault and possession of a weapon on school grounds. He was released to his parents after a detention hearing. A trial date on the matter will be set within the next 30 days.
The 17-year-old boy was treated for stab wounds and cuts at Ruby Memorial Hospital and was expected to be released Wednesday afternoon. Preston said the initial concern was blood loss but that his injuries were not life threatening. He received a number of stitches. Officers filed a juvenile referral against the boy charging him with battery.
"We know what happened this morning, now it's a backwards investigation," Preston said. "Who knew? Who knew this was going on and didn't report it. There are a lot of half-truths and quarter-truths out there.
"We'll deal with the facts and if there's things that the board of education need to deal with we'll bring it to their attention."
This wasn't the first time a student brought a weapon onto Morgantown High School property. Last year, a student brought an unloaded stolen handgun to school but was caught after another student told the school resource officer about it. Preston said the two incidents were unrelated.
The investigation into Wednesday's incident is ongoing.
