NEW YORK -- Braves right fielder Jason Heyward fractured his jaw when he was struck by a Jon Niese fastball during the sixth inning of Wednesday's 4-1 win over the Mets at Citi Field.
Heyward was transported to a Manhattan hospital to undergo X-rays, which showed the right side of his jaw fractured in two places.
With the expectation that Heyward will need four to six weeks to recover, he could be sidelined for the remainder of the regular season.
The Braves will not provide a definitive timetable until Heyward undergoes surgery in Atlanta on Thursday afternoon. Heyward's jaw has been stabilized.
This is a big blow for the Braves, who have gained their 15 1/2-game lead in the National League East with the help of Heyward, who has batted .345 with a .408 on-base percentage and a .586 slugging percentage since moving into the leadoff role on July 28. Atlanta has averaged 5.04 runs per game while going 19-4 during this span.
Heyward already missed nearly a full month early this season after undergoing an emergency appendectomy in Denver on April 22. He returned on May 17 and struggled for a few weeks. But the 24-year-old outfielder has batted .301 with a .881 OPS in the 64 games he has played dating back to June 2.
Along with his production at the plate over the past few months, Heyward also compiled strong credentials in his bid to win a second consecutive Gold Glove Award. His 24.2 UZR/150 ranks first among NL right fielders who have compiled at least 650 innings at the position this season.
While Heyward is out, the Braves will likely move Justin Upton from left to right field. Evan Gattis and Joey Terdoslavich could share time in left field. Over the past two weeks, manager Fredi Gonzalez has platooned Jordan Schafer and B.J. Upton in center field. Both Schafer or B.J. Upton could also be candidates to log time in left field.
When the Braves left New York to travel to St. Louis early Wednesday evening, they were holding out hope Heyward would receive better news. But there was definite concern given what they had witnessed.
With two outs in the sixth inning, Niese's pitch appeared to hit the ear flap of Heyward's helmet. Heyward immediately fell to the ground, while head trainer Jeff Porter and Gonzalez ran out to attend to him.
After a few minutes, Heyward stood up and walked off the field with Porter holding his arm. Schafer pinch-ran for Heyward, who was spitting blood as he went toward the dugout.
"He never lost consciousness," Gonzalez said. "He was talking the whole time when he got hit with the ball. Before they took him to the hospital, he popped his head into the dugout and said 'bye' to some of the guys. I got a chance to talk to him briefly after that."
