After many weeks of stability at the snapping position, there will be another change this Sunday with the Ravens.  Kevin McDermott, who replaced Morgan Cox in October, was placed on injured reserve today with an elbow injury and the Ravens have signed client Patrick Scales.

Scales will finally make his NFL debut this weekend against Houston.  He had been in camp with the Ravens in 2011 and 2012 and recently worked out for them after Cox’s injury.  Scales has been with four teams and snapped in 10 preseason games.

Earlier this week, the Chiefs added snapper Charley Hughlett to its practice squad after some kicking games issues in last Sunday’s game.  Hughlett, like Scales, is another example of perseverance.  Hughlett was in the 2012 NFL Draft class and has spent time with Dallas, New England, Jacksonville and Cleveland.
