Oakland Athletics starting pitcher Jarrod Parker is scheduled to meet with Dr. James Andrews on Monday after experiencing tightness in his forearm.

The San Francisco Chronicle‘s Susan Slusser was the first to report:

Comcast SportsNet California’s Joe Stiglich also reports that Parker could possibly miss the start of the regular season this spring as a result:

Bob Melvin also noted that “certainly the start of the season is in jeopardy,” according to San Francisco Chronicle reporter Susan Slusser.

It remains to be seen how severe Parker’s injury is and whether it will sideline him for an extended period of time. But for now, the A’s will be hoping for the best possible news when the 25-year-old meets with doctors early next week.

Parker has gone 25-16 with a 3.73 ERA over the past two seasons with Oakland and has made three postseason starts for the A’s as well.

Through 9.1 innings pitched in spring training, Parker holds a 10.61 ERA and a WHIP of 1.61 to go along with eight strikeouts.

Nonetheless, Parker’s long-term prognosis will go a long way in determining whether the A’s repeat as American League West champions in 2014.
