Wood joined the Magpies from Burnley in January 2022 and helped Eddie Howe's side to move from the relegation places last season to an eventual 11th-placed finish - scoring vital goals in matches against Southampton and Fulham.
The 31-year-old has made 22 appearances in all competitions for United this season, scoring on three occasions.
Everyone at Newcastle United extends their best wishes to Chris for the rest of the season.
