George Kittle has a fracture in his foot and doctors have given the tight end an eight-week recovery timetable.

Kyle Shanahan confirmed the diagnosis on Tuesday, while saying the San Francisco 49ers star is already hoping to be back on the field much sooner.

"I know it's something in his foot," Shanahan said. "It didn't show up on their X-rays, but whether on the MRIs or CT scan or something with a better resolution, it showed. It happened on that one play. I think they told me eight weeks. Kittle says two, but that's how he rolls. That's why he'll go on IR and if it's better than what they're saying, he'll have a chance to come back this year, but eight weeks is eight weeks."

Going on injured reserve means Kittle would have to miss a minimum of three weeks.
