The 34-year-old has not featured for Real Madrid since hobbling off in their opening Champions League group stage game against Celtic on September 6, missing matches against Real Mallorca, RB Leipzig and Atletico Madrid.
Benzema also missed France's Nations League games against Austria and Denmark as a result.
But the Ballon D'or hopeful is now back to full fitness as Real Madrid reconvene for a gruelling period after the international break.
"I'm pleased to be back with the team," Benzema told Real Madrid's official website.
"It's been some time [away] and I've had time to do a pre-season.
"I'm feeling very good, comfortable. I'm looking forward to the game on Sunday.
"I've been doing a lot of fitness work. I've not touched the ball but I trained for the first time today. I've done a lot of running and strength training over the past few days.
"I also worked out at home. I was a bit late back from my holidays and I didn't have much time to do a good pre-season, which is why I've done it now and I feel very good."
Real Madrid won all three games in Benzema's absence but the former Olympique Lyon striker will be itching to add to his three goals in four league games this season when play resumes this weekend.
