Neal, who SI.com ranked No. 16 in its Top 50 projected breakout players rankings, injured his foot during a game against Boston College after landing awkwardly on the foot of Eagles' guard Olivier Hanlan.
Neal had to be reevaluated once his team returned to Albuquerque from the Puerto Rico Tip Off, his father said, because he only had access to an X-Ray machine while at the tournament, not an MRI scan.
The son of New Mexico coach Craig Neal's, Neal is averaging 17 points per game on 37 percent shooting so far this season. He transferred to New Mexico from Saint Mary's in 2013.
New Mexico takes on USC at The Pit on Sunday.
