Operation “Stop the Bleeding” has just been put into effect at NBC.

After weeks of disappointing ratings, the network has chosen to make some changes on the Heroes set. Late this weekend, the show’s co-executive producers were given the boot.

According to Variety, Jesse Alexander and Jeph Loeb’s firings were a result of bad numbers all around. In addition to the show’s disappointing Monday results, production continuously exceeds the $4 million weekly budget.

This news comes on the heels of other programming decisions recently made by the Peacock network. Just last week, NBC altered its Wednesday and Friday lineups.
