Dodgers pitcher Zack Greinke will throw a bullpen session Monday, according to MLB.com.

If that goes well, there's a chance Greinke will be able to throw in a game later in the week. Greinke has been dealing with a calf injury, but it's not considered to be serious. He won't pitch in the club's Australian series, but could return early in the season.

Greinke posted a 2.63 ERA in 177 2/3 innings last year.
