Clint Frazier is quickly learning how scary a concussion can be.

The New York Yankees outfielder sustained the brain injury while making a catch against the outfield fence on Feb. 26, and hasn't played in a spring game since. But the concussion has apparently affected more than just his baseball skills, as Frazier explained to reporters his entire life has been turned upside down over the past two weeks.

"It's affecting my driving. I had a couple of scary moments driving," he said, according to Bryan Hoch of MLB.com. "I'm calling my cats the wrong names at times. But they look the same, so it's hard."

The 23-year-old added he's also experienced a "blacking-out feeling" on occasion, per Pete Caldera of NorthJersey.com, and said indoor lights are still making him nauseous.

Since suffering the concussion, Frazier's been leaving no stone unturned in his quest to shake off the problem. He even talked with Russell Wilson during the star quarterback's brief stint at Yankees camp; Wilson apparently advised him to "drink a ton of water."

Although the symptoms are still affecting him, Frazier did manage to do some basic on-field activities Saturday, including a bit of running work and some hitting off a tee. Whether the concussion will keep him off the Yankees' Opening Day roster remains to be seen, but he does feel Saturday was a small step in the right direction.

"Felt good, but foggy," he told Caldera after his workouts.

"I'm way improved from where I was two weeks ago. Still, I'm not quite over the hump."
