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 right-hander won't be on the active roster for Monday's opener 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. Verlander has been throwing lightly in an attempt to work out the tightness.

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.

Verlander is 28-24 is two seasons since starting a $180-million US, seven-year contract, slowed by core muscle surgery before the 2014 season. Winner of the 2011 AL MVP and Cy Young Awards, Verlander was 124-65 before the deal.

Detroit said reliever Bruce Rondon also will start the season on the DL because of tendinitis in his right shoulder.
