Valentine missed Wednesday's practice with a hamstring injury, Pete Dougherty of the Green Bay Press-Gazette reports.

The second-year cornerback out of Kentucky is now dealing with a hamstring issue that held him out of Wednesday's camp session. Valentine appeared in 17 games (12 starts) during his rookie campaign, recording 44 total tackles and nine passes defended. Once Valentine returns to full health, he's expected to serve as a rotational corner in the Packers' secondary.
