Dolphins running back Ronnie Brown is rehabbing from a foot injury and hinted that he may not have a future in Miami. He says he's "ahead of schedule" in his recovery and that training camp is a realistic goal. "If it was up to me, ultimately I want to be here," Brown said of Miami. "I think I've established a foundation here and I'd love to be here for the rest of my career. Unfortunately, sometimes there are decisions that have to be made." He would become a free agent if the NFL achieves a new labor agreement before March 5.
