With Laurent Robinson likely to be out this week after suffering his second concussion of the season last week, the Jacksonville Jaguars have announced some roster moves.

Chief among them was the signing of wide receiver Michael Spurlock, who was let go earlier in the week by the San Diego Chargers.

The Jaguars also promoted rookie defensive end Ryan Davis from the practice squad to the 53-man roster. To make room for Spurlock and Davis, first-year offensive lineman Daniel Baldridge and third-year defensive end Aaron Morgan were waived.
