After a sidebar, the state showed Folgate a medical record from Aug. 19, 2011 when Zimmerman sought treatment after he "started to exercise intensely with MMA." Another record from Sept. 23, 2011 states Zimmerman was involved in MMA three days per week.

The medical record from Feb. 27, 2012-the day after the shooting- says Zimmerman was "assaulted and punched in the nose." The record states Zimmerman said "EMT said his nose was broken" but an EMT has not yet testified that Zimmerman's nose was broken. Zimmerman told Folgate he needed a doctor's note for work.

According to the record, Folgate determined Zimmerman's nausea issue was caused by psychological issue from previous night. Zimmerman reportede no headache, vision change, dizziness, numbness, tingling, staggering on the morning after the shooting. He reported having nose pain, the report states, and reported have head trauma but no severe symptoms.

Folgate said she determined no stitches were necessary for Zimmerman's cuts and noted that he did have "black eyes" beneath both eyes. His nose was swollen and bruised and Folgate said Zimmerman's noise was "likely broken," black eyes, bruising, but needed an X-ray to be sure.

During cross-examination, O'Mara asked if Zimmerman's head injuries could have been caused by hitting concrete. Folgate said the head injuries "could be" consistent with being hit on the concrete and also that his injuries could be "consistent" with being punched in the nose and thrown to the ground.

Folgate also mentioned Zimmerman was already seeing a psychologist before the shooting but didn't elaborate.

The state first called Greg McKinney, an IT employee for United Security Alliance, as its first witness of Friday's court proceedings.

Prosecutor Richard Mantei questioned him about video surveillance cameras in the Retreat at Twin Lakes subdivision where Martin was shot and killed by Zimmerman in Feb. 2012.

McKinney showed video from the surveillance cameras, saying that two of the nine the complex weren't working. He said the video is 18 minutes off, meaning you would have to add 18 minutes to the time seen on the tape for the accurate timing.

Zimmerman was in court on Friday wearing a blue sport coat and dress shirt and tie. He has pleaded not guilty to second-degree murder, claiming self-defense.

Friday's testimony comes after nearly 8 hours of testimony consisting of testy exchanges between Zimmerman's defense attorney and the young woman who was on the phone with Martin shortly before he was fatally shot. 

The defense insinuated that 19-year-old Rachel Jeantel wasn't believable because of inconsistencies in her story.

But Jeantel held firm in her testimony about what she heard over the phone while talking with Martin the night the teen was shot and killed by Zimmerman, a neighborhood watch volunteer.

In her testimony, Jeantel contended that it was Zimmerman, 29, who confronted the 17-year-old Martin.
