Will Haggans' Injury Hurt Steelers?

Clark Haggans had a career day against the Patriots, but it went virtually unoticed as New England went on to beat the Steelers 23 to 20. Haggans finished with a career-high 12 tackles, but he also forced two fumbles and recorded his team-high third sack against the Patriots. He will now undergo groin surgery and be lost to the Steelers for at least 4 games. James Harrison has come up big in the past and will replace Haggans at linebacker. It remains to be seen how this will affect the Steelers' defense.
