PORTLAND, Ore. -- A reported confrontation after Friday night's high school football game between Grant and Jefferson appears to have left at least two people injured.

The altercation allegedly happened on or near the MAX platform near the Marshall High School campus, Grant’s temporary home while the school is being renovated.

One of those injured was a 15-year-old girl. She doesn't go to either school but was there to support Grant. She says she was assaulted by another girl.

“I’m like trying to curl up in a ball and then I start to feel her kick and hit my head. And like kicking my body. I don’t have any bruises but it was pretty badly in my head. I felt like I was about to lose consciousness.”

Portland Public Schools sent out a letter Sunday acknowledging reports of altercations between students off campus after the game and promised an investigation.

A district spokesperson said that investigation is ongoing with police, school security and administrators all involved.

“The principals at Jefferson and Grant are two of the best in the district. They are on it and they take it very seriously and they are really trying to figure out what happened and handle it appropriately,” said Dave Northfield.

The Portland Police Bureau asks anyone who was a victim of the attack or with information to call their non-emergency number at 503-823-3333 or to contact their appropriate school officials at their respective schools.
