49ers wide receiver Michael Crabtree could miss four to six weeks because of a lingering foot issue, according to a report.
San Francisco issued a press release announcing that Crabtree was placed on the physically unable to perform list, but they didn't say how long he'd be out.
If Crabtree can't pass a physical before the beginning of the regular season in September, he must remain on the PUP list for six weeks.
