After going through last season relatively unscathed by injuries, the Sixers weren’t as fortunate over the summer.

The Sixers announced Friday that forward Jason Smith tore the anterior cruciate ligament in his left knee during what they termed normal basketball activities on Wednesday.

“It's unfortunate that this happened, but Jason is resilient and he'll receive the best treatment available," Sixers president Ed Stefanski said. "I was there, along with Coach (Maurice) Cheeks and Tony DiLeo, when the injury occurred, which was during a routine, five-on-five drill at an NBA-approved camp held in Las Vegas. There was no contact made with Jason when he suffered the injury.

"At this point, we will continue to explore all available options in order to add an additional big man to our roster."

Smith was examined by team Physician Dr. Jack McPhilemy on Thursday evening and will receive a second opinion from Dr. Dave Altchek in the coming weeks.

No timetable has been set for his return, although ACL injuries typically require many months to heal.
