Colorado Rockies All-Star center fielder David Dahl was carted off the field after suffering what appeared to be a serious injury to his lower right leg in Friday night's 5-4 win over the visiting San Francisco Giants.
Manager Bud Black said initial tests on Dahl's ankle came back negative. The outfielder will have more tests, but the team says it believes the injury is just a significant sprain.
Black said Dahl was probably headed for a stay on the injured list.
"Anytime a guy goes down and it looks bad, I think there's a sickening feeling amongst all of us," Black said. "You hate to see those things happen to your own, and David has been so instrumental in the middle of our order, playing good defense. You just hate to see that happen ... but it could have been worse."
Dahl slightly overran a line drive to center field by Scooter Gennett in the top of the sixth inning, planting his feet to make a sudden stop and leaning back to make the catch.
But Dahl's right foot caught in the grass and he crumpled to ground, grimacing and grabbing his ankle. The game was stopped for several minutes while medical personnel assessed the injury and brought out the cart to take him from the field.
The 25-year-old Dahl began the day batting .302 with 15 home runs and 61 RBIs. He missed two months last season because of a broken right foot suffered when he fouled off a pitch. He missed all of the 2017 season because of a stress reaction in his rib cage.
"You hate to see that with David,'' said Ryan McMahon, one of his closest friends on the team. "He's been having an incredible year. Obviously he has a history of injuries. Knowing him ... and just knowing how frustrated he's been with all the stupid injuries that have happened, hopefully this is something that is not too serious and he can get back to us quick.''
