"Stuff happens," Simmons said. "Gotta live with the consequences. It's tough. [I] can't do anything about it."
The injury occurred when Simmons extended a routine single into a double. He said he saw Phillies center fielder Jason Pridie get complacent and lob the ball back into the infield. He took off.
"I always think, 'Make sure he makes a good play,' like throws the ball in hard and stuff. He didn't, so I took advantage of it," Simmons said. "You've gotta take some risks. You can't just be passive."
Though he was safe at second for a double, the headfirst slide unfortunately backfired. Eric Hinske pinch-hit for Simmons in the fifth before Jack Wilson entered as a defensive replacement.
"What a heads-up play the young man made. He ran the bases right from the very beginning, something that you preach," manager Fredi Gonzalez said. "He can slide 2,000 times and that stuff never happens to him. So it's a freak play. It's a cruel game at times. Hopefully the re-evaluation is a good one and we can minimize the damage with it."
Simmons, a 22-year-old rookie from Curacao, was hitting .296 with three homers and 15 RBIs and had dazzled with his glove in the middle of the infield.
"It's tough losing him for an extended period of time with how much he's meant for us," catcher Brian McCann said. "But we've got a guy in Jack Wilson who's been there and done that, and he's been playing for 12 years in this league. He's one of the top shortstops defensively in baseball. He's gotta fill in. He's gotta do a good job."
