The career of Antonio Bryant could be in jeopardy because of recurring knee problems, according to sources. Bryant struggled with knee issues last season. The Bengals released Bryant unexpectedly on Sunday. "He barely practiced in training camp and now this happens," said a league source. "The guy can't stay healthy at this point. He gets to the point that he's feeling good, then it swells on him again. When that keeps happening, that's a very strong indication that there are structural problems."
