STOUGHTON — A 20-year-old man was stabbed during a party at the home of University of Massachusetts Boston chancellor J. Keith Motley early Sunday morning, according to local police and a statement from Motley.

Motley was traveling at the time of the incident, according to a statement he released Sunday. He was rushing back home Sunday to learn more about what happened, he said, and he would have more to say later.

“I have learned about an incident that occurred at my residence last night and am very concerned about it as well as the health of the young man who was injured,’’ he said in the statement.

Motley was on vacation with his wife in Jamaica, according to two people with direct knowledge of his whereabouts.

Stoughton police said they received a 911 call at 2:48 a.m. Sunday reporting the stabbing at the Motleys’ home at 22 Palisades Circle. Police declined to say whether they have a suspect.

Firefighters responding to the call found the stabbing victim inside a car parked on Plain Street, after the car’s driver flagged them down, said fire Lieutenant Gregory Goldberg.

A Fire Department ambulance transported the injured man to Boston Medical Center, said Goldberg, who declined to comment on his condition.

At Motley’s Stoughton home, attorney Joseph Feaster answered the door Sunday afternoon and told a reporter the family had no statement. He said the stabbing victim is a friend of the family and that he was in stable condition.

“We are praying for him, and he is OK,’’ Feaster said.

Feaster said police have yet to interview family members.

“We haven’t had any conversations yet . . . no detectives have been by,’’ said Feaster.

About a half-dozen vehicles were parked around Motley’s home Sunday afternoon.

Neighbors contacted by a Globe reporter declined to go on the record but described the family as well-liked in the neighborhood. One neighbor said Motley hosts a Christmas party for neighbors each year.

Police are asking anyone with information about the incident to call the Stoughton police investigative unit at 781-344-2575.

Motley has been chancellor of UMass Boston since 2007. He and his wife, Angela, have two daughters, one in college at UMass Amherst and the other in high school. Motley also has an older son.

A message left on Motley’s cellphone was not returned Sunday.
