West Ham's Andy Caroll expected to be out 1 month

It's back to the treatment room for Andy Carroll.

On Thursday, West Ham United published an injury update regarding the hamstring injury Carroll suffered at AFC Bournemouth, announcing he underwent a scan and is expected to be out for one month.

The injury marks the latest in a series of ailments for Carroll. He had only returned to the pitch in November following seven months on the sidelines because of knee surgery.

"He's a positive lad, but of course he is gutted for several reasons," Slaven Bilic said, according to BBC Sport. "He felt he was back and enjoy football. It's not the end of the world, though. If everything goes well he will be back very soon so there is no reason to be negative.

"If it goes as we expect, then he will be back for a significant part of the season, the last 10-15 games, with enough time to make a huge impact on our season."

Carroll has three goals and one assist through 13 Premier League appearances this season, including a 79th-minute header that produced a 2-1 victory versus Southampton.
