"Everybody practiced today, so we're at full strength," coach Doug Marrone said Monday. "We don't expect anyone not to be available for us."
Johnson sat out the game before the Bills' bye week due to a groin injury. Woods, a rookie, missed the past two games with an ankle injury.
Sunday's game, which will be played in Toronto, will be the first time rookie quarterback EJ Manuel and his top two receivers will be on the field together since Week 5.
Although the Bills (4-7) do not have to release an injury report until Wednesday, Marrone said both receivers would have been listed as limited in Monday's practice.
"[Head trainer] Bud [Carpenter] said, 'Hey, we listed them as limited, but they truly weren't limited,'" Marrone said. "They really did everything, so I was happy with those two guys, the way they came out."
Johnson, who has battled several injuries this season, is the Bills' leading receiver with 41 catches for 471 yards and three touchdowns in nine games.
