President-elect Joe Biden injured his right foot while playing with his dog and will probably require a walking boot for several weeks, his doctor said Sunday.

Biden, 78, slipped Saturday while playing with his dog Major, one of his two German shepherds, his office said.

Late Sunday afternoon, Biden visited Delaware Orthopaedic Specialists in Newark, Del., about a half-hour from his home near Wilmington. After spending about two hours there, Biden traveled to a nearby imaging facility to have a CT scan. A cameraperson traveling with the press pool observed him walking with a limp.

A follow-up scan confirmed hairline fractures in Biden’s lateral and intermediate cuneiform bones, in his right mid-foot, according to his physician, Kevin O’Connor.

“It is anticipated that he will likely require a walking boot for several weeks,” O’Connor said.

Upon arriving at the first clinic, the van Biden was in maneuvered so reporters and photographers traveling with the president-elect could not see him as he left the motorcade and entered the doctor’s office.

The transition team also did not allow journalists off a van while Biden was inside.

A Biden spokesperson said the president-elect visited the doctor’s office on Sunday to avoid disrupting the clinic’s regularly scheduled appointments on Monday.

President Trump on Sunday night retweeted a video of Biden leaving treatment, writing, “Get well soon!”

Biden adopted Major from the Delaware Humane Association in 2018. Major is set to become the first rescue dog to live in the White House when Biden takes office in January.
