Detroit Tigers manager Jim Leyland on Monday said he was "concerned" and wondered if there could be another rotation spot to fill. He said, "I'm praying to God everything is OK."

His prayers were answered late in the afternoon when the medical report was relayed.

"I can't go into a lot of detail about what was said medically," Leyland said. "But we got the greatest news possible. Bondo has no major issues. It's just a matter of him coming back down and getting off the medication in a day or so. He can start throwing again when he's pain free.

"It's absolutely the best news we could have gotten."

Bonderman has not pitched in a game this spring but had been throwing off the mound for three and a half weeks. He underwent shoulder surgery in June to correct a circulation problem that had caused a blood clot and has not pitched in a game since then.

In what Leyland would not confirm as a related move, Rick Porcello was not used in relief Monday against Florida Southern College and will start Wednesday instead of Jon Kibler in an exhibition game here against Panama.

Porcello, 20, is a rotation candidate and said he found it difficult pitching in relief after his previous outing Thursday in Viera against the Washington Nationals.

"I'm looking for pitching," Leyland said. "You can write whatever you want."

Dontrelle Willis and Nate Robertson, who will pitch today against Venezuela, join Zach Miner as the other rotation candidates. Miner will start Thursday against the Washington Nationals.

Armando Galarraga, Edwin Jackson and Justin Verlander are set in the rotation along with a healthy Bonderman.

Tigers pitching coach Rick Knapp hopes Galarraga pitches today against Detroit for Team Venezuela because it is his scheduled day.

Until Bonderman and Galarraga return, that leaves six potential starting pitchers. Somebody will have to "piggy-back" behind another starter, and this time that will be Robertson.

Leyland would not commit to whether Porcello would get another start after Wednesday.
