Tony Pulis believes referee Chris Foy could have done more to help Ricardo Fuller in Stoke's 2-2 draw with Wolves.
Fuller was fouled twice early on, resulting in him being hampered for the rest of the match, yet no yellow cards were shown for either incident.
Pulis feels the Wolves players should have been punished and has questioned whether Fuller was given enough protection.
"The first two challenges on Ric were absolutely shocking," he told The Sentinel.
"We are being told all the time that referees are going to look after skilful players. You have a look at the back of Ric's Achilles
"He got kicked on the knee and got a cut on the back of his calf, so he struggled for the rest of the game.
"He's got a stud mark right below the knee. If that had been us playing away from home, we'd have been punished for that.
"You don't want to see players booked, but those first two tackles on Ricardo... if they aren't bookings then there isn't going to be any bookings in a game."
Pulis has also heaped praise on Matthew Etherington after the winger scored his first league goal for the club to establish a 2-0 lead just before half-time.
It was a stunning volley from the edge of the box by Etherington, while Pulis was also impressed by his overall contribution.
"I thought Matty was brilliant first half. He's most probably playing some of the best football of his life right now," hailed the Potters boss.
"In the second half as well he's looked dangerous whenever we got the ball to him, but we didn't get the ball to him often enough."
