Here’s what we know about the Erik Johnson knee injury.

 - He was playing golf at the Lake of the Ozarks when the injury happened Tuesday. (Many of the Blues’ veterans were at the lake as part of a bonding trip the players organized before the start of camp.

- Johnson injured the knee while he was trying to apply the brake and step out of his golf cart.

- An MRI was taken of the knee but it was inconclusive because of the swelling. Team doctors will wait for the swelling to subside before taking another MRI. John Davidson hopes to have an answer regarding the severity of the injury by Tuesday.

Davidson just wrapped up a conference call with reporters and here’s what he had to say:

“Erik has injured his right knee and he’s going to miss the first three days of camp. We willhave more information once we find out the extent of the injury. He’s got swelling in the knee and the MRI we did, we don’t have enough information on it because of the swelling.”

“This is a hard one to believe, but it’s the God’s honest truth . . . he was playing golf and he pulled the golf cart up to where his ball was. And he took his left leg and put it on the ground and the right leg, he sort of reached back and put it on the brake. A lot of us do it . . . I do it all the time myself. As he pushed the brake, he missed a little bit, his leg got caught under there and he slipped and that wrenched his knee.”

“I don’t know if you guys play golf, but I drive with my left leg outside the cart all the time. I always push the brake and step out all the time. I’m not going to do it anymore obviously, not that it matters. But for Erik, he’s wrenched his knee, there’s swelling there. We’re not going to speculate on this thing because we don’t know. And we’re going to have everything hopefully cleared up by Tuesday as to what it is and if there’s a length of time or not.”

“We have to re-evaluate this whole thing. We can’t run around saying there’s going to be surgery because we don’t know. We have no idea. This is obviously something that’s disturbing, there’s no question. But we don’t know the extent of it because of the swelling and we’re going to re-evaluate it over the weekend.”

“I don’t want to be evasive, I want to be honest. We don’t want to sit here and say that there’s something really serious or there’s nothing at all, because we don’t know the extent of it.”

I’m going into a chat right now, but will have more information on this story in tomorrow’s Post-Dispatch.
