Sheahan appeared in 292 regular season games for Detroit, scoring 38 goals and 60 assists for 98 points. Sadly, it appears as though injuries played a significant role in ending the veteran's career, as was put on IR back in October of 2022 and never returned to the NHL from that point on. Furthermore, he did have stints on IR that may have contributed to his decision earlier in his career as well. After all, he is only 32 years old and still has a lot of life ahead of him. He has to take into consideration his health in the future. Perhaps he could have rehabbed and made a return to the NHL, but at what cost?
"Sheahan struggled with injuries through his later career, landing on IR in 2019, 2021, and 2022. The final designation - a move to IR on October 7, 2022 - was the result of an undisclosed injury, and Sheahan would only play in eight more games in North American pros before his career came to a close."
