US President-elect Joe Biden has hairline fractures in his "mid-foot," his doctor said in a statement Sunday, after Biden slipped while playing with his dog, Major, Saturday, CNN reported.

"Initial x-rays did not show any obvious fracture, but his clinical exam warranted more detailed imaging," Dr. Kevin O'Connor said Sunday. "Follow-up CT scan confirmed hairline (small) fractures of President-elect Biden's lateral and intermediate cuneiform bones, which are in the mid-foot. It is anticipated that he will likely require a walking boot for several weeks."
