Frank Francisco, who created a stir by labeling his crosstown rivals "chickens," may have injured himself while recording a save for the Mets on Friday night against the Yankees. Francisco said his left oblique area stiffened after he cooled down after that game. The discomfort did not subside as he tried to play catch before Saturday's game. "I felt a little sore after the game last night, but I thought it was normal," Francisco said. "I put ice on. Today I feel a little worse. I went outside anyway and threw to see if it was something minor. I still feel it."
