The parents of a Bucknell University football player who died after collapsing during the first day of training camp in 2024 said Tuesday they appreciated a decision by the Pennsylvania attorney general to bring criminal charges against the strength and conditioning coach who oversaw the session. This was reported by Qazaqyia.kz citing Associated Press.

Calvin "CJ" Dickey Jr. was a freshman in July 2024 when Mark Kulbis told him and other football players to do 100 "up-downs," also known as "burpees," along with full-body plank drills, according to the attorney general's office. Dickey had sickle-cell trait, a medical condition that can increase the risk of serious injury or death following extreme exertion.

"We're at the point where we're just glad that someone is being held responsible for our son's death," Calvin Dickey Sr., of Land O' Lakes, Florida, told The Associated Press in a phone interview. "We just want to see the process through, and we're going to leave it to the attorney general to continue following the evidence."

Prosecutors announced Monday that Kulbis had been charged with felony aggravated hazing and misdemeanor counts of involuntary manslaughter, reckless endangerment and hazing.

"While the death of Calvin Dickey is tragic, Mark Kulbis did not contribute to it and is not responsible for it," his attorney, Barbara Zemlock, said in a written statement. "The strength and conditioning program that was implemented was appropriate and in accordance with the training that Mr. Kulbis received, and with applicable standards."

Sickle-cell trait, which is diagnosed through a blood test, doesn't usually affect people's daily lives. But it can cause decreased blood flow and muscle breakdown after intense exertion, dehydration or high body temperatures. In very rare cases, that can result in collapse and death.

After other deaths involving athletes with sickle-cell trait, the NCAA in 2010 began requiring that new Division I athletes be tested for the condition and alerting coaches that athletes with it should slowly build up their intensity while training and be provided adequate rest and recovery.

Dickey, who was 6-foot-5 (195 cm), had sickle-cell trait.
