According to Andrew Baggarly of the San Jose Mercury News, Bochy said the following when asked about the possibility of surgery: "As far as I know, there's no surgery. I've never heard it discussed that it's needed or required."
According to Ken Rosenthal of FoxSports.com, the 27-year-old lefty is expected to miss six to eight weeks of action.
This marks the first time in Bumgarner's career that he has been placed on the DL.
Prior to the injuries, Bumgarner was 0-3 with a 3.00 ERA, 1.074 WHIP and 28 strikeouts in 27 innings this season.
The four-time All-Star has been among the elite pitchers in the game for the past several seasons, especially in the playoffs.
Bumgarner is a three-time World Series champion, taking World Series MVP honors in 2014.
With Bumgarner on the shelf, Ty Blach will enter the starting rotation, while additional burden will be placed on Johnny Cueto, Matt Moore, Jeff Samardzija and Matt Cain.
