Hall of Fame running back Barry Sanders experienced a heart-related health scare last weekend, he said in a statement posted to social media Friday.
Sanders did not offer details on the exact nature of his condition but described the experience as "unexpected" and "a reminder of the importance of staying vigilant about our physical well-being, even when we are feeling fine."
In his statement, the Detroit Lions legend also shared his gratitude for the doctors, nurses and health care professionals who treated him.
Sanders, who turns 56 next month, went on to say that, per doctor recommendation, he is "taking this opportunity to prioritize my health and well-being."
The Lions issued their own social media post saying, "Get well soon Barry."
Sanders was a six-time All-Pro while starring for the Lions from 1989 to 1998 before his sudden retirement at age 31. One of the most electrifying players in league history, Sanders is fourth on the NFL's career rushing list with 15,269 yards in just 10 seasons, including 2,053 yards in his MVP season of 1997.
He was inducted into the Hall of Fame in 2004.
Sanders spent his entire career with the Lions, who selected him with the third overall pick in the 1989 NFL draft after his Heisman Trophy-winning season with Oklahoma State.
Last season, the Lions unveiled a statue outside Ford Field of Sanders, the first player in franchise history to receive such an honor.
