Blackburn will be shut down for the rest of the season after visiting a specialist for inflammation in his right middle finger Tuesday, Matt Kawahara of the San Francisco Chronicle reports.
The 29-year-old landed on the shelf after posting a 2.26 ERA, 1.07 WHIP and 51:17 K:BB across 71.2 innings over his first 13 starts of the season to earn a trip to the All-Star Game. However, he had a 7.94 ERA across his past eight starts before moving to the injured list last week. It's not known if he'll require surgery or whether he's expected to be ready for the start of spring training next year.
