Darren has a little swelling of the knee. He wanted to go. That was our call.

He took a knee on the helmet Tuesday. We didn't think it would be this bad, but he couldn't get full range of motion.

It's something to keep you warm. It keeps my knee from swelling up, keeps some tightness around it so it won't blow up on me when I'm out there. It's meant a lot to me.

My knee is 100 percent, so it's not like I'm getting any swelling. It's just the fact that I'm getting back used to things. It's going pretty good. I'm just trying to work on little stuff like my explosion, coming out of cuts.

The knee isn't really that bad. It's actually improving. It seems like the swelling is going down on a daily basis. This has happened in the past, too. I think being that it's just spring training right now, (it's) just for precautionary measures.

He had some swelling in the knee and when you combine that with the fact he hasn't pitched for a while, we decided to put him on the DL.
