Report: Roethlisberger expected to miss at least 4 weeks with knee injury

Pittsburgh Steelers quarterback Ben Roethlisberger is expected to miss at least four weeks with a knee injury, according to Adam Schefter of ESPN.

Roethlisberger will undergo an MRI on Monday to determine the extent of the injury. The team hopes his ACL is intact but the possibility of a season-ending injury still exists.

In Roethlisberger's absence, quarterback Michael Vick will take the reins of the high-octane Steelers offense and try to keep the team afloat in the competitive AFC North without its franchise player.

The team will likely rely heavily on its running game now that Le'Veon Bell is back from a two-game suspension. Bell chipped in 62 yards and a touchdown on the ground and 70 through the air in his return.

Wide receiver Martavis Bryant is also expected to return in Week 5 after serving a four-game suspension for violating the league's substance abuse policy.
