Chicago White Sox right-hander Lance Lynn will miss at least four weeks due to a slight tendon tear near his right knee, general manager Rick Hahn said Sunday.
Lynn is scheduled to undergo surgery on Tuesday.
Lynn was a potential starter for Friday’s season opener at Detroit. He underwent tests Sunday, and the issue was detected then.
With the four-week timetable before Lynn can throw, it could be mid- to late May before he can make his season debut.
The veteran was favoring his right leg when he left his final spring training outing Saturday in the fourth inning. He struggled in the 8-4 loss to the Arizona Diamondbacks, giving up seven runs (four earned) on seven hits over 3 2/3 innings and 79 pitches.
The White Sox have not announced their Opening Day starter. With Lynn out of the picture, right-hander Lucas Giolito is the leading option to face the Tigers.
Lynn, 34, was 11-6 with a career-best 2.69 ERA in 28 starts during his first season with the White Sox in 2021. He also was named an All-Star for the second time in his career and finish third in American League Cy Young Award voting.
In 10 seasons with the St. Louis Cardinals (2011-17), Minnesota Twins (2018), New York Yankees (2018), Texas Rangers (2019-20) and White Sox, Lynn is 115-77 in 288 appearances (264 starts) with a 3.48 ERA.
