The Chargers have signed defensive end 
Coleman (6-3, 287), who has been on the team’s practice squad, will be eligible to play in tonight’s ESPN Monday Night Football season opener against the Raiders. He wears No. 78. Coleman spent the 2007 and ’08 seasons on the team’s practice squad and has yet to appear in a regular season game. Johnson was a fourth-round choice by the Chargers in this year’s NFL Draft out of Colorado State.
