Potter said the plan was to have James play 60 minutes.
Goals from Kai Havertz and Mason Mount in the first half ensured three points against Bournemouth for the London club. The result ended a three-game losing streak for Chelsea and left them eighth on the ladder.
Before the World Cup break, Chelsea had lost four of its previous five games in all competitions and had been winless in its previous five league games.
Potter was in need of a win with his team outside the top six at Christmas for only the second time in 22 seasons.
Elsewhere, Marcus Rashford led Manchester United to a 3-0 win over Nottingham Forest, scoring the side’s opening goal and his 10th of the season, before setting up Anthony Martial for the side’s second.
It continues his impressive form that has led to United manager Erik ten Hag predicting the forward can reach 20 goals for the season.
He has already doubled his total from last term when he managed only five in a campaign disrupted by issues over fitness and form.
