Friends of a Lincoln contractor critically injured after a partial ceiling collapse at a Lincoln animal clinic have started an online fundraiser to help his family. 

Ryan Kizzier, 40, remained in critical but stable condition Wednesday. 

Authorities said he was working in the ceiling of the Nebraska Animal Medical and Emergency Center near Old Cheney and 56th St. Monday morning when part of the ceiling gave way, pinning him. Rescue crews used airbags to create a pocket to lift the rubble and to remove the victim.

Friends set up a GoFundMe page to help Kizzier and his family with expenses. 
 
"As most of you know, Ryan was involved in a work accident on Monday morning," the fundraiser organizer wrote on the page. "He remains in critical, but stable condition, and the prayer warriors are working hard, but there are still many unknowns. That being said, we wanted to start a gofundme to help Ryan and Dana with unexpected time off and medical bills they will face from this horrific accident.  Any donation helps!!!" 
 
As of Wednesday afternoon, the GoFundMe had raised $2,840 of its $2,500 goal.
 
Authorities said Tuesday morning that the Occupational Safety and Health Administration (OSHA) is investigating the incident.
