SANTA CLARA -- Wide receiver Michael Crabtree will miss a week or two of training camp with a minor injury not related to his foot or Achilles, 49ers coach Jim Harbaugh said.
Crabtree and Brandon Lloyd left practice early on Wednesday and did not take the field on Thursday. Both are on roughly the same time frame for getting back on the field, Harbaugh said.
Harbaugh did not get into specifics about the physical conditions that are keeping both Crabtree and Lloyd sidelined. Crabtree is believed to be slowed by a mild hamstring strain.
