Sen. Bernie Sanders cut his head on a shower door Friday morning and received seven stitches, his campaign told Politico.

The 77-year-old Vermont senator went to a walk-in clinic “out of precaution,” Arianna Jones, a Sanders spokeswoman said in a statement shared on Twitter by a Politico reporter.

Sanders was given a “clean bill of health” and is already back on the campaign trail, Jones said.

“The senator has proceeded with all of his scheduled events — joining a group of approximately 20 local clergy for a breakfast this morning — and looks forward to joining a roundtable with South Carolinians this afternoon to discuss how we can provide high quality affordable health care for all.”

Sanders will head to Nevada Friday night, ahead of a rally in Henderson Saturday.
