CHICAGO - A lawyer for a man dragged off a United Express flight says he suffered a concussion and broken nose and lost two front teeth.

Attorney Thomas Demetrio said at a news conference Thursday that Dr. David Dao has been discharged from a hospital but will need reconstructive surgery.

Dao was removed from the plane Sunday after he refused to give up his seat on the full flight from Chicago to Louisville.

His daughter says the family was "horrified, shocked and sickened" to learn and see what happened.

Crystal Pepper says seeing her father removed from the Sunday flight was "exacerbated" by the fact it was caught on video and widely distributed.

Demetrio says the experience was more horrifying than when Dao left Vietnam during the fall of Saigon.

Demetrio says he "probably" will file a lawsuit on Dao's behalf.

United Airlines CEO Oscar Munoz has said he was "ashamed" when he saw the video and that the airline is reviewing its policies. Munoz says law enforcement won't be involved in removing passengers in the future.

The airline has issued another apology to the man who was forcibly removed from a full flight, saying "we remain steadfast in our commitment to make this right."

Attorney Thomas Demetrio also said neither Dao nor his family had heard directly from United since the incident.

In its statement, United insisted again that CEO Oscar Munoz and the airline called Dao numerous times to apologize. Munoz said Wednesday that he had left a message for Dao.

United spokeswoman Megan McCarthy told The Associated Press she saw call logs that showed Munoz and United's customer care team had reached out to Dao.
