But Laurent is continuing his non-contact rehabilitation and hopes to be back in contention for their European clash with Leinster on April 27.
"I'm feeling fine - it's been two months since I began training, so physically I'm in good shape," said Lauret.
"It's great to come back into a group where there is a good atmosphere.
"Before Gloucester I told the boys 'go ahead, give it your all and qualify because I can go with you to the semifinals.
"They have done that and put in a lot of commitment to qualify. That was a great success and there's also the opportunity to qualify for next season's Heineken Cup."
Biarritz face a formidable challenge in the face of Leinster, who conquered Europe last season.
But Lauret insists he will hold nothing back when he returns to action and his only worry is not knowing precisely when he will get back on the pitch.
"The only worry I have is not knowing whenI'm playing. The next game in my mind is the semi-final against Leinster.
"My teammates have toiled for three months, when I was not there,to try to qualify and get a place in the last four. Will I be able to rejoin them? I do not know.
"It may be the last game of the championship. But my aim is to play in the semi-final and then the last game against Stade Francais.
"If I can comeback before that I will be very happy. But otherwise, it's Leinster and May 4."
Tanguy Molcard has fill the void left by Lauret. The 22-year-old started in the quarter-final victory over Gloucester Rugby and will not want to give up the number six jersey without a fight.
