Midfielder Johnson limped out of Saturday's 1-0 FA Cup third-round defeat by Manchester City with a recurrence of a hamstring problem, although there does not appear to be any tear.
A club spokesman said: "Adam Johnson suffered a tight hamstring on Saturday and he will be subject to a late test before Saturday's game against Swansea."
However, full-back Taylor, who has not played a senior game since September because of an ankle ligament injury, will undergo surgery on a double hernia on Tuesday.
