John Kerry Releases First Photo Since Bike Crash

But can the secretary of state heal in time for nuclear talks with Iran?

He had surgery exactly one week ago to set his broken femur at Massachusetts General Hospital and has remained there since while he undoes physical therapy.

When an interim deal was reached in April, the negotiating parties conducted eight straight days of talks, often on just a few hours of sleep. Kerry is known for his frenetic pace, but last week’s bike accident has forced him to slow down.

But today, eight days later, asked again if Kerry plans to attend the talks, State Department spokesman Jeff Rathke was less emphatic.

"That's something that, you know, he and his doctors will have to, you know, keep under -- keep under review, so I don't have -- I don't have a timeline," Rathke said.

If it’s eventually determined that Kerry is unable to travel, it’s possible that the talks could be moved to New York City. But U.S. officials said that so far there have been no discussions about changing venues.
