Instead of spending next week with his fellow All-Stars in San Diego, Boston Red Sox closer Craig Kimbrel will be going under the knife. 

News came down today that the right-handed reliever has been placed on the disabled list with a slight tear of the medial meniscus in his left knee.

Kimbrel will undergo surgery to repair the cartilage around the tear Monday and is expected to miss 3-6 weeks.

The news of the injury further explains Boston's most recent trade, in which they swapped a couple of prospects for veteran closer Brad Ziegler from the Arizona Diamondbacks, earlier today.

Ziegler and the team's former closer Koji Uehara, who had been in the set up role thus far this season, will share closing duties in Kimbrel's absence, according to ESPN's Scott Lauber.

Kimbrel, who suffered the injury shagging fly balls during batting practice Friday, had posted a 3.55 ERA with 17 saves in 19 opportunities so far this season. He also made his fifth career All-Star team this season.
