Quintana underwent microscopic surgery Thursday to address a left thumb laceration and is expected to remain out for two weeks before resuming a throwing program, Jordan Bastian of MLB.com reports.
According to a press release from the Cubs, Quintana suffered the injury while washing dishes at his home in Miami last weekend, with the wound on his thumb requiring five stitches. When he met with doctors for further evaluation of the injury, Quintana was recommended to undergo surgery after nerve damage was detected in the thumb. The Cubs will see where Quintana stands in his recovery when he's re-evaluated in mid-July, but because he'll miss out on some necessary ramp-up time following MLB's shutdown, he looks highly unlikely to be ready for the Cubs' Opening Day game July 23 or 24. His expected absence could pave the way for both Tyler Chatwood and Alec Mills to crack the rotation as the Cubs' fourth and fifth starters.
