NFL.com is reporting Michael Crabtree has a slight stress fracture in his left foot that will require surgery to insert a screw, according to league sources.
I'm following up on this right now, but obviously this is going to have an effect on who Seattle drafts at No. 4, with most drafts pegging Crabtree as Seattle's selection.
Seattle head coach Jim Mora also talked today. I'll have more on the Crabtree injury and the Mora conversation later.
UPDATE: NFL Network's Adam Schefter is now saying the injury will require Crabtree to miss 10 weeks. Obviously this is big news, and makes it even more riskier for Seattle or anybody else to take Crabtree that high.
Never miss a local story.
Here's Schefter's story. According to his report, the injury was revealed during medical testing at the combine, and Crabtree most likely will cancel his Pro Day in Dallas scheduled for next month.
