The Trotters skipper left the 22-year old with damaged ankle ligaments which should have him sidelined for four weeks with his early challenge in the 5-0 loss at Reebok Stadium.
Earlier this week, Davies defended himself and now Coyle has leapt to the striker’s defence, asking why there has been so much exposure of the incident.
"To be honest I don't know what there was to sort out," Coyle told Sky Sports News. "Kevin Davies made a challenge, it was a free kick, there was no doubt about it.
"He certainly never went in with any malice to hurt Tom Cleverley, who he's wished a speedy recovery. There was no intent from Kevin to try and hurt the lad.
"He's an outstanding young player who picked up an injury on the back of it. That was it, it happens up and down the country, every game.
"Is it because it was Manchester United, who are the champions? I don't know.
He added: "What he's had to deal with for me has been well over the top.
"Kevin, being the lad he is, phoned Tom on Saturday night to make sure he was going to be OK.
From our point of view at Bolton Wanderers we wish the lad a speedy recovery but it was just a mistimed challenge and that's all it was."
