Melissa Gilbert was rushed to hospital during Monday's broadcast of Dancing With the Stars after she injured her head on the dance floor.
Gilbert was doing her Paso Doble performance with partner Maksim Chmerkovskiy when she hit her head. She complained about dizziness after the bump.
Chmerkovskiy also fell during the routine, but the two received a 22 out of a possible 30 from the judges. Judge Len Goodman blamed the fall on a slippery floor.
Gilbert isn't the first to be injured on the show. Last year, Kym Johnson was injured during rehearsal with partner Hines Ward.
