49ers head coach Jim Harbaugh has "seen progress" from first-round rookie WR A.J. Jenkins.
"He's been on his assignments. He's executed well when he's been out there. He's given great effort and football rewards that effort," added Harbaugh. Jenkins was active for the first time last week against the Rams but did not play a single snap. With Mario Manningham listed as doubtful with a shoulder injury, Jenkins is expected to officially make his debut in Week 14 versus the Dolphins.
