The Pittsburgh Steelers signed quarterback Michael Vick to a one-year contract worth up to $1 million. The former Pro Bowl quarterback joined the Steelers after backup Bruce Gradkowski dislocated a finger in his left hand that's going to require surgery. Gradkowski was placed on injured reserve. Vick, 35, passed for 604 yards, three touchdowns and two interceptions last season. Vick made the Pro Bowl in 2010 when he passed for 3,018 yards and 21 touchdowns with the Philadelphia Eagles. "There's not a throw on the field he can't make from an arm strength standpoint," Pittsburgh coach Mike Tomlin said. "He's a very experienced guy at what he does at this point in his career and the mobility is still unique even at 35."
