Dave Roberts, whose left knee was injured on his last day of work at Action News after 31 years, says he suffered a tear of his meniscus and will get surgery.

After doing a live weather shot Friday, he was on his way to the studio -- where staff and family were gathered -- when he stumbled in a hallway.

His colleague Adam Joseph fetched an ice pack.
