Preston North End manager Ryan Lowe has admitted his side have been dealing with a sickness bug in the camp ahead of their trip to Bristol City.
The Robins host Preston on Wednesday at Ashton Gate with Nigel Pearson's side on a run of five matches without a win. Their opponents will head into the contest buoyed by a 3-2 victory at Norwich on Saturday.
It moved Lowe's side up to eighth in the Championship and their victory was made more impressive by the fact a handful of players were throwing up before and during the contest.
