Newcastle players were forced to adjust to winter weather after training in the snow on their return from a warm-weather training camp in Saudi Arabia.
The Magpies travelled to Riyadh for the camp, with Eddie Howe's side returning on December 10 after a week in Saudi Arabia's capital.
The trip was Newcastle's second to the country since the controversial takeover led by the Saudi Public Investment Fund.
Howe, who said the visit to Saudi Arabia was the best thing for the team during the World Cup break, saw his side earn a 5-0 win over Al-Hilal during the trip.
Newcastle have since returned to Tyneside, with the squad seen being put through its paces at their Benton training ground.
Sven Botman, Joe Willock, Miguel Almiron and Chris Wood were among those seen braving the winter weather as Newcastle prepare for the resumption of the club season.
Wood had been substituted in the first half against Al-Hilal with an injury.
Newcastle will resume the Premier League campaign in third place, after recording eight wins from 15 games during the first part of the season.
Almiron's form has contributed significantly to the impressive start to the season, with the Paraguayan international having scored eight times in the league.
Allan Saint-Maximin was also seen training as the French winger seeks to regain full fitness, with injuries having limited his involvement this season.
Saint-Maximin has been restricted to just 33 minutes of action in the Premier League since suffering a hamstring injury in August, but got 77 minutes under his belt against Al-Hilal.
Newcastle will host La Liga side Rayo Vallecano in their second mid-season friendly on Saturday, before hosting Bournemouth in the Carabao Cup fourth round on December 20.
The Magpies will travel to Leicester on Boxing Day to resume their Premier League campaign and push for Champions League qualification.
