The 25-year-old was stretchered off after scoring his first Premier League goal of the season in December against Watford following a collision with the Hornets goalkeeper Heurelho Gomes.
However, the attacker, excited after returning to training, is looking forward to a positive outing for David Wagner’s men against the Eagles at the John Smith's Stadium on Saturday.
“I’m really happy [to be back in training]; I think it’s been a long time since I’ve been out and with the team,” Kachunga told HTTV.
“Last week I trained with the team and this week was the proper week with them on the grass. I’m really happy to be back.
“I think everyone who plays football knows how hard it is when you can only stay in the gym, train on your own and only go on the grass with the fitness coach to do your runs, doing all the stuff you have to do.
“I’m happy to be back with the team, to make jokes with my teammates and have fun on the pitch.
“We’ve got some really important games coming up. I think the next game against Crystal Palace is really important for us at home.
“We need the three points to make a big step in the right direction for us. I hope I have a good week and then hopefully on the weekend I might be on the grass.”
Prior to Kachunga’s injury, he has made 19 appearances in all competitions for the Terriers this season.
Last term, he scored 12 times in 45 English Championship outings to help the club secure promotion to the top-flight.
Huddersfield are three places above the relegation zone and a win against struggling Crystal Palace will boost their chances of staying in the Premier League next season.
