macke_5-25.jpgFollowing his bizarre on-air comments last week, CNBC contributor Jeff Macke‘s future with the network is in doubt.

Business Insider’s Joe Weisenthal reports Macke will not be back on CNBC, while sources tell TVNewser no decision has been made.

Still, we hear Macke’s appearance on Fast Money the following night was being watched closely by Susan Krakower, the show’s co-creator and CNBC VP. A “backup” trader was ready in case Macke was deemed unable to go on-air.

Macke has not been on CNBC since last Wednesday’s appearance.

A CNBC spokesperson gave TVNewser a “no comment” on the situation.
