CHICAGO — The Cubs were already in the market for bullpen help this offseason. That need became even more apparent on Thursday, when it was revealed that Brandon Morrow underwent a procedure on his right elbow last month.

Speaking with reporters on Thursday, Cubs president of operations Theo Epstein announced that Morrow had an arthroscopic debridement performed on his throwing elbow on Nov. 6 to clean up some cartilage in the joint. Morrow is not scheduled to resume throwing until around Feb. 6, putting his availability for the start of the season in jeopardy.

Last offseason, the Cubs signed Morrow to a two-year, $21 million contract that includes a $12 million team option (or $3 million buyout) for 2020. In 35 appearances out of Chicago’s bullpen last season, the right-hander posted a 1.47 ERA with 31 strikeouts, nine walks and 22 saves. Morrow landed on the disabled list on July 19 and was declared done for the season in September due to right forearm iammation and a nagging bone bruise.
