Manager Garry Monk expressed his dissatisfaction at referee Tim Robinson’s decision to award Hoilett only a yellow card for a tackle he described as ‘reckless’ and ‘out of control’.
The tackle took place just after the hour mark and saw Palmer replaced by Julian Borner as Wednesday chased the game.
And asked about the condition of Palmer, Monk said his full-back, a near ever-present when available this season, was likely to be struggling for their next game, against Hull City on Wednesday.

He said: “We can’t afford that.
“We’ll have to see and assess it. Right now his ankle is swollen, which is not good for us.
“I don’t know. Normally you can tell in 24 or 48 hours, so we’ll have to wait for the swelling to go down to get it scanned and we’ll see how it all goes.”
Monk said he ‘didn’t understand’ the decision to award Hoilett a yellow, but well stopped short as framing it as an excuse for a frustrating result.
He said: “I’ve got a player on the treatment player with an ankle the size of a balloon and if you can’t see that from four yards away as the fourth official or the referee, you have to ask them.
“But we’re not using that as an excuse.”
