Sylvester Stallone's stepbrother is up against the ropes after being busted for alleged first-degree murder.

Bryan Rhodes, the stepson of Sly's dad Frank (so no blood relation), is suspected of being a go-between in an oxy drug deal gone bad, reports the Palm Beach Post. The popo claim Rhodes set up the robbery, targeting a reputed drug dealer, which ended in the dealer's murder.

Sly's rep said she didn't expect him to comment.
