J.R. Smith will undergo an MRI on Tuesday to check out the extent of a right knee contusion.

David Blatt says he believes Smith locked legs with Nerlens Noel during the first quarter.

Blatt's demeanor while talking about Smith made the injury sound serious.

"We're anxiously waiting to see how he responds tonight and if necessary, he'll do an MRI tomorrow. But hopefully he's OK," Blatt said. "That's a scary thing."
