Riverside County and California firefighters responded to the 911 call at 1:45 p.m.
Turci Yuri, 34, and Jakob Jensen, 31, were hospitalized in critical condition, according to the Riverside County Sheriff's Dept. The two suffered head and chest injuries. The two were in surgery Friday afternoon.
The two were part of a group visiting from Canada. There were paramedics on the ground that were part of the group, according to the sheriff's department. The paramedics were able to administer immediate medical attention.
One jumper is from Denmark and the other from Italy. They are both considered experienced jumpers.
The accident happened at Perris Valley Sky Diving, located at 2091 Goetz Rd.
Dan Brodsky-Chenfield, manager of the skydiving company, said the two were injured in a mid-air collision about 200 feet above the ground.
On March 31, two skydiving instructors were killed when they collided and their parachutes deflated more than 300 feet in the air at the same location.
Friday afternoon's accident occurred a day before a planned memorial jump - known as an "ash dive" - to honor the victims of the previous crash.
