Cardinals linebacker Kylie Fitts, a 2018 sixth-round pick who spent his last three seasons with the team, announced his retirement on Friday, citing his recent string of concussions.
“After 21 years of playing, football has come to an end for me,” Fitts wrote on Instagram. “Due to too many concussions and the severity of my recent one, it is no longer safe for me to continue to play. I am so grateful for this game and everything it has taught and brought into my life. Thank you to all my coaches and teammates throughout my career.
