Crabtree, who became the first 49ers' pass-catcher since 2003 to collect 1,000 receiving yards last year, could be added to 53-man roster at any time before Nov. 26. Last month, Jim Harbaugh said Crabtree could be ready to play by as a soon as mid-November. The 49ers visit the Saints on Nov. 17, travel to meet Washington on Nov. 25 and, of course, host the Seahawks on Dec. 8.
