Fournier was traded from the Orlando Magic to the Celtics in March, but admitted he has been struggling with focus and depth perception as he continues to recover from the virus. "It's like I have a concussion," 28-year-old Fournier told reporters after the Celtics' 129-119 loss to the Portland Trail Blazers on Sunday. "Right now, it's actually doing a little bit better. But at first it's like the bright lights were bothering my eyes and my vision was blurry and everything was just going too fast for me. "At times, I'm really struggling to focus and my eyes keep struggling to focus on one thing. My depth perception is really bad right now. But I saw a specialist, she gave me some exercises and hopefully it will get better."
