STATE COLLEGE, Pa. (AP) – Penn State says coach Joe Paterno is undergoing medical tests on his right arm and hip at a hospital after a player ran into him during practice on Sunday. The school announced yesterday that Paterno walked away from the collision with a receiver who was running a route. The 84-year-old says he’s “fine” and expects to be back on the practice field “soon.”  Dr. Wayne Sebastianelli, Penn State director of athletic medicine, said in a statement that it doesn’t appear surgery will be required. The school said Paterno could be released in the next 24 hours.  A person familiar with the team says doctors are evaluating Paterno’s shoulder and pelvis but there is no firm diagnosis on the extent of the injuries.  Paterno is entering his 46th season as Penn State’s head coach and is the winningest coach in the history of major college football with 401 victories.
