(Santa Clara, CA)  --  Two recent first-round picks for the 49ers are dealing with injuries.  Both defensive end Nick Bosa and receiver Brandon Aiyuk are week-to-week.  Bosa strained a leg muscle, and Aiyuk is recovering from a hamstring injury.  Bosa was the second overall pick last year, and the Niners selected Aiyuk 25th overall this year.
