DAVIE (AP) - Brandon Marshall milled about the Miami Dolphins practice field, donning an orange cap and sneakers instead of a helmet and cleats.
He'll be doing a lot more of that over the next few weeks.
Marshall is recovering from surgery, the details of which neither he nor Dolphins coach Tony Sparano would disclose Wednesday, when most of the wide receiver's new teammates took part in one of Miami's organized team activity days, or offseason practice. Sparano indicated Marshall would be back for training camp.
"We don't play a game today," Sparano said. "We play a game down the road somewhere. ... No disappointment at all. He's been here for eight weeks now, throwing and catching and doing all the things necessary. I mean, he was throwing and catching the day that the procedure was done. So, not real concerned about it."
The Denver Post reported Marshall had hip surgery two weeks ago in Vail, Colo., calling it "a cleanup procedure." Marshall's agent, Kennard McGuire, did not respond to either an e-mail or telephone message left by The AP seeking comment.
"It was something that came up, we needed to get it cleaned up, and we did," Sparano said.
Marshall, who also had hip surgery before the 2009 season and has said he played in 2008 with a hip tear, shook off questions about his on-field absence.
"It's definitely frustrating, but you know, some things you can't control," said Marshall, who didn't appear to be wearing any braces or show any other obvious sign of injury. "In my past, I learned that, not to worry myself and hold my head down when I can't control it. I'm just going to do the best I can with the mental reps and prepare myself that way."
As the workout began, Marshall took a spot on an exercise bike set up behind one of the end zones, then joined teammates, often stopping to chat with Ricky Williams, Ronnie Brown and others while following along with the plays and trying to pick up whatever nuances of the offense he could.
