Rockies pitcher Juan Nicasio was hit in the head by a line drive and carted off the field in the second inning of Colorado's game against the Nationals.

Nicasio was taken to the hospital where he was "resting comfortably while undergoing a battery of tests," the Rockies announced.

The right-hander was struck by a ball off the bat of Washington's Ian Desmond. The ball slammed into the right side of Nicasio's head with a smack and caromed away, rolling over the first-base line.

Nicasio went down and lay flat on the mound for several minutes as he was attended to by training staff. He was moved onto a cart by four medical personnel, helped by teammate Todd Helton and manager Jim Tracy.

He could be seen blinking and moving his hands and legs before he was put on a stability board and loaded onto a cart.
