The surgery involved taking the middle piece of the patella tendon and using it to replace the PCL.
It was the start of some dark times for Grobes. He lost his scholarship to Penn State and his daughter, who was born in 1996, passed away the next summer, and his best friend died that August.
"I went into a pretty deep depression and I never thought I would play again," he said. "I wasn't one of those people who was motivated to get back on the field. That wasn't the case. I was done."
Then he meet Jamie, who would become his wife.
"She loves football and I credit her with saving my life," he said. "I don't know what she saw in me, I don't know what her family saw in me. She was 20, I was 22. To fall in love with a guy who had two kids, not doing anything with himself and spiraling out of control, she brought me out of it."
Grobes would honor his eventual wife when he returned to the field in 1999 by wearing her favorite number, 7.
"She said it was her lucky number and we got married on 7-7-07," he said. "I credit everything I've done in my life to football and my wife."
At Jamie's request, Grobes went looking to get back to college to play football when he ran into an old friend after dropping off game film at King's College in Wilkes-Barre.
That chance meeting led to his minor-league career which began with the Wilkes-Barre Blaze and spanned seven years until 2006 when his PCL snapped in his final game. In all, Grobes had three knee surgeries.
Grobes attended Luzerne College and took business courses and on Sept. 11, 2001, he enlisted in the United States Air Force. He earned the rank of Senior Airman. Jamie was in basic training with the Air Force on 9-11.
