Detroit Lions defensive lineman John Penisini announced his retirement via social media Saturday morning.
"I have made the decision to retire from football," Penisini wrote on Instagram. "I’m definitely going to miss my teammates and the coaching staff but I’m glad I got to experience it. I’m happy and excited for whatever life has for me.
"For my family, friends, teammates, coaches and all the people who supported my dream along the way I appreciate and love you guys."
A sixth-round draft pick out of Utah in 2020, Penisini went on to play 576 snaps as a rookie.
