Holding his cards close to the vest, Warren County High School football player K’Rojhn Calbert announced his commitment Wednesday to attend the University of Tennessee after being courted by over a baker’s dozen universities.“First and foremost, I want to thank God for this day. Next I want to thank my grandmother for being a great role model in my life. She’s taught me many things, especially to be respectful with the many sacrifices she makes every day,” Calbert said during his commitment speech.
