Brandon Marshall: I feel in "amazing shape"

Chicago Bears wide receiver Brandon Marshall has revealed that he feels in "amazing shape" heading into the new season.

The 29-year-old has struggled throughout the off-season with a hip injury after undergoing surgery earlier in the year.

"I'm always concerned about my body. It doesn't matter if it's a little scratch, I'm always concerned," Marshall told the Chicago Tribune.

"So coming off my third hip surgery, structurally, everything is good. The joint is in amazing shape. So that's exciting."

Chicago face the Cincinnati Bengals in their season opener on Sunday.
