When coach Tommy Johnson left Riverdale High School on Friday night, his biggest concern wasn’t an offense which failed to produce positive yardage, it was the growing number of players who seem destined to be on the sideline watching for a while.Coach Johnson and the Pioneers cut their scrimmage against Riverdale and Franklin High School short Friday after Warren County had a number of players sustain injuries, ranging from minor to possibly severe.Coach Johnson made the decision after the Pioneers had played a quarter against both opponents. For Johnson, it was about getting to the start of the regular season as healthy as possible.“It was a risk I wasn’t willing to take,” said Johnson. “I wanted to get our guys back home and rested because the real season begins in two weeks.”Senior starting linebacker and center MaCrae Thomsen was the first to go down.
