Head coach Doug Marrone said afterwards that both are dealing with ankle soreness.
"His ankle was sore today, and it’s good because tomorrow we’re off, so we just wanted to give him two days off. He shouldn’t be a problem," Marrone said of Pears.
Otherwise, the Bills were close to full health on Monday, with cornerback Stephon Gilmore (wrist) and offensive lineman Doug Legursky (knee) -- who both have longer-term injuries -- the only players not spotted.
The Bills will practice next on Wednesday.
