The Raiders special teams coverage units have taken a beating this offseason.
Brynden Trawick and Darren Bates took heftier paychecks from the Titans last week.
The Raiders lost another key component on Saturday afternoon, when receiver Andre Holmes signed with the Buffalo Bills. NFL Network reports the deal is worth $6.5 million over three years.
This one foreshadowed. National reports of a pact with Buffalo surfaced on Wednesday due to a contract offer run through the NFLPA system that looked like an agreed-upon deal.
Holmes refuted the completed deal on Twitter, a social media service he rarely uses.
