Mikaela Shiffrin said she will still race the slalom and team combined at worlds but said she's "not there yet" with giant slalom.

Mikaela Shiffrin says she is dealing with post-traumatic stress disorder following a crash in November and will not defend her gold medal in giant slalom at the Alpine skiing world championships.
