Kyle Schwarber suffers left ankle sprain in outfield collision; MRI set

— -- PHOENIX -- Chicago Cubs left fielder Kyle Schwarber suffered a left ankle sprain Thursday night in a scary collision with center fielder Dexter Fowler as both chased a line drive from Jean Segura of the Arizona Diamondbacks. 

Fowler made contact with Schwarber's legs as the two converged in left-center during the second inning of the Cubs' 14-6 win.

The second-year player rolled around on the warning track before athletic trainers attended to him.

He remained down for several more minutes before getting to his feet with the assistance of the trainers and limping off to a cart, which took him off the field. 

The Cubs said Schwarber sprained his left ankle and that initial X-rays were negative. He is scheduled to have an MRI on Friday. 

A source also said Schwarber tweaked his left knee on the play. 

Segura raced around the basepaths and scored an inside-the-park home run on the play. It was his second home run of the game, and it gave Arizona a 4-2 lead. 

Schwarber is one of the heralded young stars for the World Series-favorite Cubs. The fourth overall pick in the 2014 draft hit .246 with 16 home runs and 43 RBIs in just 69 games last year. He also is the team's backup catcher and was scheduled to get his first start behind the plate Friday. 

Kris Bryant moved from third base to left field in place of Schwarber, and  Tommy La Stella took over at third.
