Grand Prix dressage rider Silva Martin, who suffered a serious head injury in a fall from a young horse on Wednesday, March 5, is not out of the woods yet.

Martin began smiling and speaking a bit on Friday and was able to communicate even better yesterday, but today “she’s had a bit of a battle,” according to her husband, four-star eventer Boyd Martin.

“I got a phone call saying that she’d gone unconscious again, so they were worried that she’d started bleeding [again] in her brain,” said Boyd, following his win in the intermediate horse trial division at Red Hills in Tallahassee, Fla., this afternoon.

“She was transferred out of intensive care this morning and was moved into another part of the hospital, and then she started losing consciousness and becoming unresponsive,” Boyd explained. “So they immediately did another CT scan, and the good news is that the scan is showing no more progression in the bleeding in the brain, and she’s regained being responsive a bit.”

In addition to Silva’s friends and family, Dr. Mark Hart, a former four-star owner who sits on the U.S. Equestrian Federation’s Safety Committee, has been of assisting and offering substantial support.

“He’s been overseeing the whole thing and sort of triple-checking the scans and MRIs and also sort of explaining what’s on the horizon and stuff,” Boyd said. “He’s an exceptional character, and I think without him I’d be very confused and unsure. He’s been deputized on this, and all her scans are being sent to him, so he’s reading them all and checking in on her progress. He’s basically saying, ‘Look, on paper, it’s not getting worse.’ “

Silva remains under the care of doctors at Delray Medical Center in Delray Beach, Fla., and Boyd said she has not been transferred back into the Intensive Care Unit.
