Lawrence-Douglas County Fire & Medical responded to a call for medical assistance at Kansas University's Phi Gamma Delta fraternity house, 1540 La., about 7 p.m. Wednesday.
A freshman fraternity member was injured after falling during an event at a KU sorority house and was then transported to Lawrence Memorial Hospital by ambulance, university spokesman Todd Cohen said.
The male student stood up, fell down and was injured to the point that his fraternity brothers brought him back to their house from the sorority. Phi Gamma Delta President Chris Lupton said the man was "somewhat unresponsive," so they called 911.
Lupton said the student was in good condition but chipped a tooth after hitting his head.
Lawrence police said the incident happened at the Kappa Kappa Gamma sorority, 1 Gower Place, while the fraternity was having a joint function with the sorority, and that there was alcohol involved.
Lawrence police said they did not expect any criminal charges, but would put together an informational report and forward it on to the university. Cohen declined to name the student, pending notification of his family.
