"Bills linebacker Shawne Merriman said Friday he needs to give his sore Achilles tendon enough time to fully heal, and he does not know how long it will take.

"It's coming along, but it's still the same situation it was a few weeks ago. Just wait and see what happens," Merriman said after the Bills' practice.

"My main thing is just to get it healthy. It's been there for a year. I haven't had many other problems other than that. It's been there constantly -- on and off -- for a year now, and I never really had a chance to take care of it. I've been pretty healthy the last couple of years -- other than that. It's unfortunate, but I have to get it taken care of."

Merriman has been inactive the past three weeks since being claimed off waivers from San Diego. He is out for Sunday's game against Pittsburgh."
