Zola has only played a hand full of games since the turn of the year and will be hoping to see the season out on a high as he aims for more goals to the 16 already scored this season.
Crewe manager Dario Gradi told the official site "Calvin has had his set backs this season, and he was doing very well at one stage. Just before his ankle flared up this time he was training super, but injuries have been his let down. He is coming along ok at the moment though, and the physio's tell me that he should be ok to rejoin full training on Monday so hopefully he can stay injury free for the rest of the season.
"We need to get him going again though, he trains well but then doesn't always transfer that onto the pitch, so if we can rectify that, he can become a fantastic player. Unfortunately though, we'll be without him this weekend."
