Marko Arnautovic has been pictured training with the West Ham United first team ahead of the club's Premier League home match against Watford on Saturday.
The forward has missed the Hammers' last three matches because of a hamstring problem sustained in the 1-1 draw with Bournemouth on January 20.
Prior to his injury, Arnautovic had scored six goals in 10 matches to help David Moyes's charges climb out of the Premier League relegation zone.
On Thursday, new Hammers recruit Patrice Evra posted a video of his first training session since joining on a short-term deal as a free agent following his release from Marseille.
In the video, Arnautovic appears at around 23 seconds in, during a team warm-up.
West Ham have failed to win a match since losing the 28-year-old to injury, suffering defeats to Wigan Athletic and Brighton & Hove Albion and drawing with Crystal Palace.
