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.” http://sports.yahoo.com/nfl/news;_ylt=Ai18j0hd2khKQaGDt_qXxwU5nYcB?slug=ap-dolphins-marshall
