Pittsburgh Steelers legend Jack Ham was taken to the hospital after suffering a medical emergency in Seattle.

The Hall of Fame linebacker won four Super Bowl titles during a remarkable NFL career that saw him spend more than a decade with the Steelers.

Ham works as an analyst on Penn State radio and he was in Seattle ahead of the Nittany Lions' clash with Washington on Saturday.

But Penn State revealed in a statement that the 77-year-old 'experienced a medical emergency earlier today and was transported to the UW Medical Center, where he is being treated.'

No further details were released and there has been no update on his condition.

Ham played as a linebacker for Penn State and has worked as a radio analyst for the Nittany Lions since 2000.

He helped the Steelers win four Super Bowl championships in the space of six seasons during a decorated career in Pittsburgh.

Ham was also an eight-time Pro Bowler who was named to both the NFL's All-Decade team for the 1970s and the NFL's 100th Anniversary All-Time team.

The 77-year-old was inducted into the Pro Football Hall of Fame in 1988 and the College Football Hall of Fame in 1990.

Penn State went on to win 28-25 against the Washington Huskies on Saturday.
