PHOENIX -- With about $7 million in cap space remaining, according to NFLPA records updated Tuesday, the Buffalo Bills don't have much room to sign more free agents.
"We're at a point now that if we do anything, it's going to be just some minimum [salary] guys," general manager Doug Whaley said Tuesday at the NFL owners meetings. "We have to have room for our draft choices and we also have room for injury replacements during the season. So we're pretty much tapped out of the free-agent market."
But with a need for depth at linebacker, the Bills are keeping open the possibility of re-signing linebacker Brandon Spikes, who remains an unrestricted free agent.
"We're going to reach out to him and I'm going to call him when I get back," Whaley said. "Does it fit what we're offering and where he is in his career? We would love to have him back but again, it's got to be a fit on both parts."
Spikes played less than 50 percent of defensive snaps last season for the Bills and would undoubtedly remain in a part-time, run-stopping role if he returned to the Bills, who have Nigel Bradham and Preston Brown atop their depth chart at linebacker.
There has been little reported interest in Spikes, a former second-round pick in 2010, since he hit the free-agent market earlier this month.
