Chicago Cubs starting pitcher Jose Quintana underwent surgery on Monday for a laceration on the thumb of his throwing hand, the team said in a statement.
During the surgery, doctors identified a lacerated nerve in the thumb and surgically repaired it.
The left-hander suffered the cut last Saturday in his Miami home while washing dishes and received five stitches.
Monday’s microscopic surgery was originally scheduled to determine the extent of the injury.
The team said Quintana is expected to resume his throwing program in about two weeks but did not say whether or not the 2016 All-Star would be ready for the start of the MLB season later this month.
The Cubs acquired Quintana in a midseason trade in 2017 with the cross-town Chicago White Sox for a haul of top prospects, including outfielder Eloy Jimenez.
While Quintana's numbers have been worse since joining the Cubs, he has remained a reliable and durable part of the rotation, one of only four MLB pitchers to start at least 30 games in each of the last seven seasons.
The 31-year-old Colombian is 33-23 in his Cubs career with a 4.23 ERA after going 50-54 with a 3.51 ERA with the White Sox.
If Quintana is unable to pitch at the start of the season, the Cubs may turn to Tyler Chatwood or Alec Mills to fill out a rotation that features veterans Jon Lester, Kyle Hendricks and Yu Darvish.
