Carroll had knee surgery in February 2015

West Ham have a new injury worry after striker Andy Carroll was substituted with a hamstring problem in the Hammers' 3-1 win at Bournemouth.

Carroll was forced off after 15 minutes and manager Slaven Bilic says the injury will be assessed on Wednesday.

"It's a big blow for us because he started this game good," said Bilic.

"I don't understand it because we're resting the players. We're not training a lot. We can only hope it won't last that long."

The 27-year-old has scored two goals in West Ham's past four games after returning in September 2015 following seven months out for knee surgery.

A former Newcastle player, Carroll joined West Ham from Liverpool for a club record £15m in June 2013.
