Chicago Cubs reliever Kyuji Fujikawa will undergo Tommy John surgery on his right elbow, the team announced Wednesday.

Fujikawa injured the arm while pitching in Sunday's 10-inning win over Cincinnati. He was placed on the 15-day disabled list on Monday with a muscular strain of his right forearm.

The 32-year-old Fujikawa, who is in the first year of a two-year, $9.5 million deal, underwent an MRI on Tuesday, which revealed the severity of his injury. He spent nearly a month on the DL earlier this season with a related issue.

No date or doctor has yet been selected for Fujikawa's season-ending surgery.

Fujikawa signed with the Cubs this past offseason after playing eight seasons in Japan. In 12 appearances with the Cubs, the right-hander was 1-1 with a 5.25 ERA and two saves.

The Cubs claimed pitcher Alex Burnett off waivers from the Baltimore Orioles on Monday.
