WBBM (Chicago) Weekend Anchor Mai Martinez has gone M-I-A from the station.

Martinez announced that she’s on medical leave for an undisclosed ailment.

“Thank you Chicago for embracing this Southern transplant 13yrs ago,” Martinez tweeted. “I’m so grateful for my time at @cbschicago & all of you. Some of you are asking why I’m not on TV or social media. Please do not worry. I am STILL w/CBS 2, but currently on medical leave & hope to return soon.”

She wrote in a Facebook post that she was “working with a great team of doctors at Rush and beyond,” adding: “I hope to be feeling better and back on air very soon.” She declined to comment further.

Martinez joined the station back in 2006.
