Albion boss claims the tackle could have broken both of the Irish striker's legs and is disappointed the incident will overshadow his team's performance and win at Villa Park
Alan Hutton's tackle on Long appeared to be high and two-footed but the Scottish defender received only a warning from referee Phil Dowd.
"Very pleased with the result, very pleased with the performance, very disappointed about Shane Long's injury, angered by the challenge still," Hodgson told reporters after the match.
"So before any of you start talking to me about red cards, be very careful, because if ever I've seen a challenge that merited a red card, it was Hutton's on Long.
"It's a scan job, but he's lucky, he could have had two broken legs."
Villa's Chris Herd was later sent off for a perceived stamp on Jonas Olsson but Hodgson had little sympathy for the midfielder and only added that he felt his side's performance should not be overshadowed by the incident.
"The referee refereed the game well, but as in all football matches these days it all revolves around the incidents so tomorrow our performance, our passing, our movement will be largely ignored because they want to be discussing whether Herd should or should not have been sent off," he said.
"But I just want to make it clear from my point of view that I don't care about that.
"The guy left his foot on him, what else is there to say?
"It was a moment of madness from the player which happens in football and unfortunately him and Aston Villa had to pay a high price for it."Hodgson was pleased with his side's display at both ends of the pitch and thought that Darren Bent's opener for the home side from the penalty spot came against the run of play.
"We played very, very well," he said. "I thought we were playing well before we gave away that penalty with another ludicrous mix-up which we’re not happy about.
"But I thought we looked very comfortable at that stage, creating lots of opportunities, looking very dangerous up-front.
"When they went down to 10 men I thought we controlled the game but at the same time I thought our defensive work was good because Ben Foster had a quiet afternoon."The result and performance was only soured, according to Hodgson, by Long's injury, which he could only hope was not ligament damage.
"We're a small squad with a relatively small squad of good players and to lose players for long periods of time is going to affect us, there's no question about that," he said.
"So that does sour it, there's no question in my mind.
"Maybe we’ll be lucky, maybe the scan will show it wasn't as bad as all that.
"The doctor doesn’t think it’s a cruciate [injury] which is good, but I'm afraid there's a lot of ligaments in knees which can keep you out of football for a long time."
