• Spurs' manager 'not worried' by nine goals in 10 league games
• He stresses results that have put his team in fourth place
The Tottenham Hotspur goalkeeper needed lengthy treatment after diving at the feet of the striker Romelu Lukaku during the second half of the goalless draw at Goodison Park.
Brad Friedel looked ready to come on as Lloris was led off the field but the Frenchman appeared to argue for the right to play on. Villas-Boas said: "Hugo still doesn't recall everything about the incident. It was a very difficult moment for us and I am happy he is well.
"I made the call to keep him on the pitch because of the signs he was giving. He was determined to continue and looked concentrated, driven and focused enough for me not to make the call to replace him. The saves he did after the incident proved that right."
The Spurs manager issued a staunch defence of his side's goals' record this season as they missed the chance to go second in the Premier League.
The draw means Spurs have scored only nine league goals this season – three of them penalties. Only Hull have scored fewer among the top 10 teams in the Premier League. Villas-Boas bristled at the post-match questions over his team's lack of penetration and pointed to a return of 30 goals from 17 matches in all competitions – including 15 in the Europa League and six in the Capital One Cup – as evidence of a functioning cutting edge.
"I don't think it is dramatic," he said. "We are on 30 goals in 17 games and it is the second highest ever at the club at this stage so I don't worry about that. Hull are sitting 10th and we are fourth. The chances are coming and sometimes they go your way and the opponent is not there to stop it. The team is creating more chances and more shots. I can carry on about all the good statistics and others can carry on about all the negative statistics and the debate will go nowhere.
"At the moment it is results that have put us in fourth and in one of the spots for the Champions League. You can have more goals, less goals. We all want excitement but right now the team is doing extremely well."
He conceded his team should have been more clinical during a dominant first-half display. "I am not disappointed with that result. In the end it was a good result and the only time Everton had a good go at us was in the last 25 to 30 minutes. We had a very good game and could have been a bit more clinical.
"I am still happy with the team, but because of what Everton did in the final stages it was a fair result. We couldn't be more happy with the players. They pressed well and had great motivation. There was a lot at stake for both teams with the chance to go second and I think we did extremely well."
Villas-Boas accepted the referee, Kevin Friend, was correct not to award a penalty when Jan Vertonghen fell under a Seamus Coleman challenge in the first half and again when the roles were reversed in the second half. "There was minimal contact," he said. Everton's manager, Roberto Martínez, however, believed Vertonghen should have been punished for his touch on the defender.
"They tell you decisions level themselves out over a season but it doesn't happen," Martínez said. "We had a similar situation at Villa and at the Etihad [Stadium]. Seamus gets impeded. He doesn't over-react, he gets back on his feet and it should have been a penalty."
