Jewel -- whose husband, Ty Murray, is one of the final four stars competing on DWTS -- took the former Bachelor contestant to task for not performing on this week's show due to an injury.
"I think the rule about 'judging a rehearsal if the person is too injured to perform' was weird both times they have used it," wrote on her hubby's MySpace blog.
The rule, which states that a contestant too injured to compete on the live show will be judged on their rehearsal footage, was used Monday when Rycroft suffered a rib injury and was in too much pain to perform. It was also put into practice earlier in the season when Steve-O hurt his back and couldn't dance.
"If you're too hurt to compete, then you can't compete," she wrote.
The singer, who was originally slated to compete on the eighth season of DWTS but backed out of the competition due to a knee injury, joked that if she "were to be on the show, I might change my mind."
Still, the fan of rodeos and bull riding thinks that Rycroft shouldn't have gotten through to the next round.
"As bad as I felt for Melissa, who I hope feels better and comes back, I'm used to our cowboy athletes that live by the rule: 'Ride hurt or dont get a score,'" Jewel wrote. "It may seem harsh, but it seems like the only way to keep things honest."
