ORCHARD PARK, N.Y. (AP) - Bills linebacker Takeo Spikes did not practise on Friday because of a lingering right hamstring injury and will likely miss Buffalo's game against Minnesota on Sunday. Coach **** Jauron said after Friday's practice that Spikes is on "the downside of 50-50," but added the player will be a gametime decision. Spikes, who remains questionable on the official injury report, had practised fully on Wednesday and Thursday before sitting out Friday. "It didn't feel as good as we had hoped after yesterday's practice, so we decided to hold him out," Jauron said. "We're going to be cautious until we can see him run and burst." Spikes, a two-time Pro Bowl selection, has missed the last two games and most of a third because of the injury. He was hurt in the first quarter of a 19-17 opening loss at New England on Sept. 10. He is trying to come back from a torn right Achilles tendon sustained last season in Week 3.
