Marquez fractured his finger after a friend rode over it after he fell off a motorcross bike three weeks ago. He underwent surgery on the injured finger soon after and competed in the MotoGP event in Jerez two weeks ago with the aid of painkillers.
Having had some time off to recover, Marquez believes that his finger should not cause him any problems during the Grand Prix de France in Le Mans on Sunday.
"Here we can say that the finger is already at 100%," Marquez said during a pre-race press conference. "It's a little bigger than usual but I already have the power that was the biggest problem in Jerez. We will see. We did a couple of laps on Monday. For the test we try a few things and here we have some things to try and improve on the exit of the corner."
The Spaniard finished second in Jerez despite his finger injury, and has his sights set on taking top honours in France this weekend even though he is not a big fan of the circuit.
Marquez is determined to close the 26-point gap to championship leader Valentino Rossi, and knows a win his the best way to start reeling the Italian in.
"It's years ago I got my first pole position here," Marquez said. "I remember that it was half wet half dry. It's a circuit that I get my first victory in Moto2. I didn't like a lot but I normally get a good rhythm. We will try to do a good weekend and see the weather too but it looks like Sunday will be ok. I'm ready to start."
Marquez, who currently occupies fourth place in the standings, does not think it's time to panic about Rossi's advantage as the season is just four races old.
"Last year I arrive here in a completely different position," he said. "This year I'm fourth in the championship and 26 points behind Valentino. Still there are 14 races [to go]. It's not a panic inside the team so we will try to continue like we did until now because I think we have a good level."
