The Pittsburgh Steelers have said that they will look into why so many players sustained injuries during the 2012 season.

Quarterbacks Ben Roethlisberger and Byron Leftwich, safety Troy Polamalu and wide receiver Antonio Brown were among the players to miss multiple games with injuries in the regular season.

Steelers president Art Rooney II told the team's website: "It does happen sort of in cycles, and hopefully we're getting through this cycle. But having said that I don't think we can just sit here and believe we'll come to the end of the cycle.

"We have to look at everything we're doing, and we will look at everything we're doing, from the training and conditioning side of things, from a practice side of things and see if there are things we can do to get better.

"Conditioning is something that's always evolving, people are always coming up with new ideas on how to train, and so we'll look at all of that."

The Steelers missed the playoffs for just the second time in six seasons.
