What would an installment of ABC's Dancing with the Stars be without the drama? Last night’s semifinals were no exception. It came courtesy of pro-dancer Lindsay Arnold when the Season 25 front-runner was injured rehearsing a troupe dance on Sunday, leaving partner Jordan Fisher in doubt that the couple could even compete. (Arnold had to dance wearing a knee brace.) As if that injury wasn't enough, Arnold inadvertently scratched Fisher’s cornea during Monday’s dress rehearsal, causing the star a great deal of anguish. Despite slipping by two points last night they still finished with a solid 59 out of a possible 60 -- and they are still in the lead heading into the finals.
