Toronto Blue Jays starter Marcus Stroman will not be ready to start on Opening Day, manager John Gibbons announced on Monday.

The 26-year-old has been dealing with inflammation in his right shoulder, an MRI earlier this spring showed no structural damage.

While the starter was ruled out of the opener, it is possible he starts during the first week of the season.

Stroman was 13-9 with a 3.09 ERA last season, his fourth with the Jays.

Gibbons also announced that outfielder Randal Grichuk is day-to-day with a rib cage issue.

The 26-year-old is in his first season with the Jays, after being acquired in a January deal with the St. Louis Cardinals for Conner Greene and Dominic Leone.
