The Fall Out Boy bassist sustained the injury during a concert in New Orleans, Louisiana, last month (Oct07) after jumping off a set of speakers on stage.
And the 28-year-old is happy to let his girlfriend take care of him.
He says, "When I'm being hard-headed and I don't want to elevate it (his foot), she says, 'No, put it on the pillow!'.
"When I try to get in the shower by myself and am going to end up falling on the hotel room floor, she's good at stopping me."
