The 76ers announced Thursday that McCain has been diagnosed with a pulmonary contusion and has not displayed symptoms consistent with a concussion. The rookie guard will be out for Friday's preseason game against the Magic and will be evaluated daily, Adam Aaronson of PhillyVoice.com reports.

While McCain will be sidelined for Philadelphia's preseason finale, it appears he has avoided a concussion. The rookie guard's next chance to suit up is the team's regular-season opener against Milwaukee on Oct. 23. McCain is expected to compete for bench minutes in the 76er's backcourt this season.
