Yankees outfielder Chris Dickerson had an MRI that confirmed a concussion, but he is suffering from no heavy symptoms. He doesn't think he'll be the first member of the team to land on baseball's new seven-day disabled list specifically for concussions. Dickerson did not blame Mike Gonzalez, the Baltimore reliever who threw the pitch that shattered the brim of his helmet Wednesday night. He also did not believe Gonzalez did it on purpose. "Absolutely not," Dickerson said. The two men talked behind the batting cage Thursday night and embraced.
