Stoke boss Tony Pulis has bemoaned the fact Ryan Shawcross must now miss two games following Saturday's red card at Fulham.
Fulham wound up 2-0 winners, with the second goal coming from the spot after Shawcross had hauled down Clint Dempsey in the box.
The away side struggled to find the form that has made them a terrifying prospect at the Britannia, with a strong bench unable to make an impact after the sending off.
Referee Stuart Attwell had little choice but to reduce the Potters to ten men, yet Pulis feels the rule needs looking at.
"I'm looking at it and it's two bodies coming together. He's been sent off, we've been penalised with them scoring the second goal and now he misses another two games," Pulis told Sky Sports.
"I think it's a harsh thing to have to accept when it looks as though the kid's almost on the way down waiting to be touched.
"It's not only that it's the two games [suspension] as well. It's desperately disappointing for us. I do think at times people will have to look at [the rule]."
Pulis admitted that he had few issues with the result itself, but pointed to a number of chances that could have created a very different outcome.
"I've not really any complaints [about the result]. I think the penalty decision obviously changed the game," added Pulis.
"First half I'd say Fulham were the better team although we've had four or five great opportunities today without really playing well. Obviously the penalty and the sending off then kills you.
"We've got good players ready to come on but when you're 2-0 down and ten men it's very difficult for the forwards.
"Having said that, Kenwyne has had two great headers that have gone over the bar. On another day he scores those two."
