Detroit Tigers pitcher Justin Verlander is headed to the disabled list for the first time in his major- league career.

The Tigers said Thursday the 32-year-old righthander won't be on the active roster for the opener Monday against Minnesota because of tightness in his right triceps. He was scratched from his Thursday start and no timetable has been announced for when he will pitch again.

"I don't think this is going to be a long-term issue," Tigers manager Brad Ausmus said. "After throwing yesterday, he said he felt as good or better today."

Detroit will make his DL stint retroactive, making it possible the six-time all-star could start the sixth game of the season, on April 12 at Cleveland.

Hamilton fate must wait

Commissioner Rob Manfred said a decision on possible discipline against Los Angeles Angels star Josh Hamilton likely will happen after opening day.

Manfred had been hoping for a decision before the Angels start play Monday at Seattle.

Hamilton has had a long history of drug and alcohol abuse, and has been suspended in the past. The Angels said Hamilton met with baseball officials last month, but neither side provided details.
