The Manchester United center back played an unimpressive showing before he was replaced after picking an injury against PSG on Wednesday.
The 24-year-old was handed a starting role as a right-back against the Ligue 1 leaders in their 3-1 Champions League win at Parc des Princes.
The Ivorian defender delivered an unimpressive showing in the unfamiliar role and paid less attention as Juan Bernat sneaked in at the far-post to pull PSG level after Romelu Lukaku had put the Red Devils in front.
“It would have been negligent to keep Bailly on the pitch to be honest” said Rio Ferdinand.
“It’s a blessing he got injured and had to come off.”
