Doctor suggests Kerby Joseph might need to consider retirement

Dr. Jimmy Liao, a physician, has raised concerns about Kerby Joseph's knee injury, advising that he may need to contemplate retirement for long-term health. Joseph, who missed much of the previous season, is currently on the Physically Unable to Perform list as he begins training camp with the Detroit Lions. Liao's claims stem from the potential damage to Joseph's knee, highlighting issues that could affect his mobility and athletic performance. However, Liao has not examined Joseph and his comments are speculative, lacking any formal announcement from Joseph's medical team or the Lions. The team's cautious approach to Joseph's recovery may reflect a desire to monitor how his knee responds to football activities going forward.
