Joey Gallo's winter of work has been stalled several weeks and could be done altogether.

Gallo left the game between Magallanes and Margarita on Thursday after pulling up while running to first on a ground ball. He clutched his left knee right where the hamstring connects to the knee. He was attended to on the field by trainers but walked off under his own power. Rangers officials called the injury a "moderate" strain of the hamstring and said he would be down "a few weeks."

Gallo had planned to stay in Venezuela until Thanksgiving and get in an extra month worth of at-bats after a disappointing finish to 2016. It is unclear whether Gallo will return to Venezuela when the injury is healed. The Venezuelan regular season ends in December.

It was just Gallo's third winter league game in Venezuela. He was 2 for 6 with a home run and five RBIs in his first two games.
