With J.J. Barea sidelined for potentially an extended period of time with a left calf strain — Rick Carlisle said it might have to wait until after the All-Star Game — the Mavs’ backcourt depth took a hit Friday night.

Matthews earned his “Iron Man” nickname, so while the significance of his injury is unknown at this time, it’s safe to subtract a bit of time off simply because Matthews is such a tough dude. Stay tuned for updates on his status.
