BALTIMORE - Jim Johnson didn't have the most pleasant of weeks after the Baltimore Orioles' 10-game road trip.
Baltimore's closer checked himself into the hospital Monday night and ended up spending four nights there.
Johnson rejoined the Orioles Friday after doctors struggled to diagnose the right-hander.
They eventually discovered it was food poisoning and released him after he kept two meals down.
"It wasn't enjoyable," Johnson told reporters. "It was pretty bad."
As for when he could return to pitching, Baltimore manager Buck Showalter isn't sure and neither is Johnson.
"We're just kind of playing it by ear right now. I'm going to do what I can, but not overdo it," Johnson told reporters. "We'll see where I'm at. I just tell them how I feel after I do certain things. We'll just make a game plan. I'm not doing anything structured, it's kind of based upon how I feel.
"I'm just kind of lethargic I guess right now. I've been laying on my back for four days. Just getting on my feet, running around, doing some [cardio] stuff was good."
Infielder Robert Andino also was reinstated from the paternity list after missing two games to be with his wife for the birth of their third child.
Baltimore optioned right-hander Jason Berken to Class AAA Norfolk to make room. Berken didn't pitch in his two days with the club.
