The Steelers placed quarterback Dennis Dixon on injured reserve Saturday after suffering from a knee injury while Ben Roethlisberger is expected to go back on the team after ending his four-game suspension.

Dennis Dixon had injured his knee  during the Pittsburgh Steelers match against the Tennessee Titans on their second week. Steelers’ had won with 19-11 score, but they had to end Dixon’s season.

Dixon led Pittsburgh’s victory during the past two seasons. In one of his games, he made 22-of-32 for the 254 yard with only one interception. Last week, he underwent knee surgery to repair the tear on his left knee’s cartilage. He is expected to miss about 6-weeks to recuperate.

On the other hand, Ben Roethlisberger began the season with a four-game suspension after being accused of sexual assault. He is scheduled to return to game, after Steelers’ Sunday game against Baltimore.

This is Roethlisberger’s 7th season with the Steelers. He was chosen by his team as the 11th overall in the NFL 2004 Draft. He helped the Steelers win the Super Bowl XL with a 21-10 score against the Seattle Seahawks.

While Roethlisberger is yet to return on Monday, the Steelers with a 3-0 win for the season, are missing a quarterback for this Sunday’s match. The Steelers have been undefeated with several Super Bowl titles and AFC Championship games. Their most recent championship was the Super Bowl XLII last February 1, 2009.
