From "Nomar: Return to DL is frustrating" at MLBPLAYERS.com:
It's an understatement to say I'm extremely frustrated to be back on the disabled list.
I was starting to feel pretty good in my return from my hand injury. Things were starting to work for me the way I wanted. I was on the field, trying to help the team. That's all I cared about. Then this happened.
As soon as it happened, I knew I had pulled my calf. When I lunged after the ball I felt it right away. I walked around to see how it would feel. Ideally, I wanted to get through the rest of the inning and get checked out in the dugout. I tried to walk it off, but I couldn't. At that point, I knew I was in trouble.
It doesn't matter if I hurt myself on an innocent-looking play or a tough play. It's still a devastating thing. When it first happened, I didn't want to talk to anybody about it. I had worked so hard to get back, then to have something like this just put me right back on the DL -- it was just too frustrating.
This injury seems similar to a calf injury I had last year from which it took about two weeks to get back. Every time it happens it can be different, though, so you never know. I don't know how long it will take this time. Last year, once I came back, it didn't really bother me. I was all right. Time will tell how the injury reacts this time.
I didn't feel any worse the day after the injury than I thought I might. That's good. On the other hand, it never feels great when you have trouble walking. I don't have my normal gallop or anything. The first order will be rest to get the swelling down.
When you do come back from an injury, you try not to protect yourself or think about it subconsciously. But sometimes your body does that instinctively. That's why sometimes you see a pitcher with a sprained ankle suddenly hurt his shoulder. Everything is connected.
The plan for me now is to stay back from the East Coast road trip. That way I can get treatment all day and do what I need to do.
As for baseball activity, I can obviously throw, but I think I will be off baseball activity for a week, at least. It's about not putting any stress on the calf. The first order of the rehab process is rest, then you build your strength back up.
