Bruins forward Tyler Seguin shaping up to have a breakout season, but looming in the background is a question about his long-term health. Seguin has a congenital hip condition that makes him more susceptible to a hip injury, according to league and team sources. The condition could lead to an injury that requires surgery and potentially shortens his career, the sources said, but is not a concern for the short-term, nor is it affecting him presently.
