Still recovering from his third hip surgery, Chicago Bears wide receiver Brandon Marshall expressed frustration Tuesday with his current physical state.

Marshall indicated the Bears might be pushing a little harder than he'd like as Chicago attempts to prep its star wideout for the Sept. 8 regular-season opener against Cincinnati.

"It's one of those things where you may be rushed a little bit, and some people might think I need to be farther on than where I am," Marshall said. "So it's a little frustrating not being where I want to be right now, and maybe pushed a little bit. So we'll see."

Marshall missed the majority of the offseason after undergoing arthroscopic hip surgery. Despite frequent days off throughout training camp and the preseason, Marshall still has experienced some soreness in the hip, even as the breaks have affected his conditioning level.

Bears coach Marc Trestman said he couldn't comment specifically about Marshall's feeling that he might be getting rushed back into action.

"I know this: Brandon is working his tail off to try to get himself ready. He feels a sense of urgency because the season is 10 days away," Trestman said. "He's a highly competitive man, an elite player. He can only comment on how he feels.

"You saw him out on the field at Soldier Field. So you saw that he does have those moments where he can practice and work at a very high level. There's been days that haven't gone so well for him, and then he'll bounce back. I don't know how he feels. I know he's trying to push himself through. I know he's doing everything he can to try and get himself ready."

Asked whether he's received enough repetitions this preseason, Marshall said, "No, I haven't."

Marshall dropped two passes thrown his way during last week's win over the Oakland Raiders, just one outing removed from hauling in four passes, including one for a touchdown, against the San Diego Chargers. In that game, quarterback Jay Cutler directed each of his five passes toward Marshall.

"I'm just trying to get healthy for Week 1," Marshall said. "So you've got to have a game plan coming off surgery, a third hip surgery. So yeah, I'm not where I want to be right now. For myself, mentally [and] physically, we need to pick it up a little more."

In 2012, Marshall's first season with the Bears, he established the club's single-season record for receptions (118), and receiving yards (1,508). Marshall also caught eight touchdowns, tied for sixth on the Bears' single-season list.

In the new offense brought in by Trestman, Marshall said he's still trying to figure out his role.

"Mentally, as far as understanding plays, I know where I'm supposed to be. I know where I'm supposed to line up," Marshall said. "Now, it's getting a feel for it and having more experience in the offense. I'm still trying to figure out my role and my place in this offense; trying to get healthy, and we'll see where it takes us."
