Chicago White Sox reliever Liam Hendriks will be reinstated to the active roster Monday, the team announced, after he missed the first two months of the season while being treated for non-Hodgkin lymphoma.

The White Sox posted a video montage to their Twitter page Sunday that featured messages from White Sox players and coaches welcoming back Hendriks.

Hendriks, 34, was diagnosed with stage 4 non-Hodgkin lymphoma in early December and completed his final round of chemotherapy in early April. He began a rehab assignment earlier this month, appearing in six games for Triple-A Charlotte.

Hendriks threw several batting practice sessions over the past 10 days against teammates before declaring himself ready Sunday. Hendriks announced his diagnosis Jan. 9. His return comes just shy of six months since the diagnosis.

The White Sox bullpen has struggled in Hendriks’ absence, though it has been better in May after lefty Garrett Crochet returned from Tommy John surgery and righty Joe Kelly went on a scoreless streak that lasted 10 appearances. But overall Chicago has struggled through the first two months, heading into Memorial Day with a 22-33 record.

Hendriks is in the final season of a three-year, $54 million contract, with a $15 million club option for 2024.

The White Sox host the Los Angeles Angels on Monday night.
