Recently appointed West Ham manager David Moyes looks to be without Javier Hernandez for his first game against Watford on Sunday, according to The Times.
Hernandez recently sustained a hamstring injury whilst on international duty for Mexico in his side's 3-3 draw against Belgium on Friday.
The injury forced the 29-year-old to pull out of Monday's night game against Poland and now looks to miss Moyes' first game in charge of the Hammers at Vicarage Road.
Chicharito has four goals in 11 Premier League appearances since his £16m move from Bayer Leverkusen this summer, making him the club's top scorer this season as West Ham sit 18th in the table.
The news comes after Moyes was full of praise for the Mexican to allay any fear of being frozen out at the Olympic Stadium under his tenure like he was when the pair were at Manchester United.
Speaking to The Guardian, Moyes said: "He's a top goalscorer, a brilliant finisher.
"It was difficult for him at United because I had Robin van Persie, Wayne Rooney, Danny Welbeck, Shinji Kagawa, so there was lots of competition.
"But he'll be treated the same here - if he's playing well and scoring, no problems. If he not, it will be the same as the rest."
