The 34-year-old was granted compassionate leave by the Baggies following the death of his agent and now, following talks on Wednesday, the striker will stay at the Hawthorns
The Frenchman penned a one-year deal with the club in July, but looked to cut his Hawthorns stay short when Baggies boss Steve Clarke announced the striker's intention to retire from professional football due to the bereavement.
However, following talks between the pair on Wednesday, Clarke has confirmed Anelka will remain at West Brom and is "looking forward" to returning to the pitch.
"Anelka came in yesterday [Wednesday] and told me he was looking forward to helping Albion for the rest of the season," Clarke told reporters at a press conference on Thursday.
Anelka enjoyed a prolific pre-season - netting seven goals in as many game - but failed to find the net on his debut against Southampton on the opening day of the Premier League season.
A club statement read on Wednesday read: "Albion can confirm that Nicola Anelka will resume first-team training tomorrow and be available for selection for Sunday’s game against Swansea.
"The striker was excused from club duty for the fixtures against Everton and Newport on compassionate grounds and, having met with head coach Steve Clarke today, he will rejoin his team-mates tomorrow [Thursday]."
