"I'm feeling better, much better," Brown said Tuesday morning at Bright House Field. "I'm not going to lie to you guys, I was a little nervous there before the MRI.
"Hopefully I can be back on the field in another week or so."
Brown said he expects to start running in the next few days. In the meantime, he is receiving treatment, riding a bike and playing catch. He has not hit since Thursday.
"Hopefully I can be ready for Opening Day," he said. "That's the goal right now, but we'll see what happens. I'm excited it wasn't a tear or anything like that. We're moving in the right direction."
If Brown is unable to play Opening Day, the Phillies could open with Ben Revere, Odubel Herrera and Grady Sizemore or Darin Ruf in the outfield.
