The Republican lawmaker went home on Monday after receiving treatment for the concussion and a “minor rob fracture” in the fall last week, according to his office.
“At the advice of his physician, the next step will be a period of physical therapy at an inpatient rehabilitation facility before he returns home,” his communications director David Popp said in a statement.
“Over the course of treatment this weekend, the Leader’s medical team discovered that he also suffered a minor rib fracture on Wednesday, for which he is also being treated.”
The 81-year-old senate minority leader tripped and fell while at the Waldorf Astoria hotel in the US capital, a property which used to be owned by Donald Trump.
“The Leader and Secretary Chao are deeply thankful for the skilled medical care, prayers, and kindness they have received,” Mr Popp’s statement added.
The Kentucky lawmaker suffered a fractured shoulder in a fall at home in 2019.
