In his second season with the Steelers following his release by the Browns, Haden is coming off an injury-plagued 2017. He missed five games and recorded a career-low 20 tackles.
"My groin's good. My knee's good. I'm feeling healthy," he said, per Jeremy Fowler of ESPN.com. "I was able to get a full offseason workout. My last two offseasons I haven't been able to train like I wanted to. This year, I got after training like I never have before."
Haden's injury will leave a void in the Steelers secondary that won't be easily filled if he misses extended time.
Mike Hilton will likely step into an increased role with Haden out of the lineup. The 24-year-old recorded 64 tackles during his rookie season in 2017, mostly playing slot corner.
Haden has not played a full NFL season since 2010.
