Stoke manager Tony Pulis criticised Pavel Pogrebnyak's challenge on Wilson Palacios during his side's 2-1 defeat at Fulham.
A late Ryan Shawcross header gave the Potters hope at Craven Cottage but Fulham held out for the three points on home soil.
Stoke had Robert Huth sent off last week for a tackle on Sunderland's David Meyler and Pulis believes Russian Pogrebnyak, who scored on his debut, should have at least been dealt a card.
"Last week we had Robert Huth sent off for a challenge where he's pulled two feet away, we've seen a challenge today from the Russian lad on Palacios where he catches Wilson just below the knee," Pulis said.
"The referee doesn't see it, Kevin Friend the fourth official is stood where we've seen it and it was a very poor challenge.
"The kid doesn't even get a card. The inconsistency this year in the Premier League in respect to incidents has been really poor.
"I'm really disappointed. Last week we had a player sent off, and for a worse challenge the lad doesn't even get a yellow card."
On his side's performance, Pulis added: "I thought we did very well second half, I thought we were the better team in the second half.
"We're not getting the breaks at the moment and we gave them a leg up with two poor goals.
"I was really pleased with how we fought back but we're not getting the breaks."
