Pennsylvania State University officials are addressing a racist letter sent to a football player.

Penn State defensive tackle Antonio Shelton tweeted an image of the letter Monday.

The letter attacks player Jonathan Sutherland's hairstyle, calling dreadlocks disgusting and unattractive.

It goes on to attack NFL players for their appearance as well.

Penn State head coach James Franklin said the message in the letter does not fit with the spirit of football.

"You know that the football that I know and love brings people together and embraces differences: black, white, brown, Catholic, Jewish, or Muslim, rich or poor, rural or urban, Republican or Democrat," said Franklin. "Long hair, short hair, no hair. They're all in that locker room together. Teams all over this country are the purest form of humanity that we have. We don't judge. We embrace differences. We live. We learn. We grow. We support and we defend each other. We're a family."

The letter was signed by a Penn State graduate named Dave Petersen.

The university reacted to the letter in a tweet, stating, "Its content does not align with our values. We strongly condemn this message or any message of intolerance."
