Melissa Gilbert - Gilbert Hospitalised With Concussion

The former Little House on The Prairie star took to the dancefloor for a routine with professional partner Maksim Chmerkovskiy, but viewers noticed she was missing when all the competitors appeared together at the end of the episode.

The show's host Tom Bergeron told the audience that Gilbert had to leave the studio to see a doctor after hurting herself during the routine.

He said, "She injured herself and as a precaution she's gone to the hospital to get checked out."

Gilbert suffered a mild concussion and whiplash, but she has assured fans she will be back on her feet as soon as possible.

In a post on her Twitter.com page, she writes, "I'm alright. Mild concussion and whiplash. Very soon I will be safely home resting and being taken care of."
