Gary Rowett’s men emerged 2-1 victors despite having Etebo sent off before the break for his challenge on Keogh and are now up to 12th in the league table.
Rowett also played down the incident with Johnson after the game.
He said: “Someone said originally that Bradley had bit Joe, but I think Joe said it wasn’t too bad. Certainly we’re not going to have any complaints.
“I spoke to the referee, saying it’s not a problem and we don’t want anything further to be looked at. To me, it was just part of a melee.”

Meanwhile, Frank Lampard’s Derby sit seventh following the defeat.
Lampard felt that the game was there for the taking when Stoke went down to 10 men, with Derby also losing Curtis Davies to an Achilles injury before half-time, with the defender stretchered off.
He said: “We are disappointed to lose a game against 10 men when you get yourself at 1-1. From there it is ours to win. The mistake gives them the second goal, then it is a difficult situation to break down 10 men behind the ball, so we’re disappointed.
“We could have done more in the last half an hour to get back and at least draw the game.
“Joe Allen and Gary Rowett just said there wasn’t much in it (the alleged incident), I haven’t seen it again, so I can’t give any information other than that.”
