Martinez:"Naismith is okay. We will check him over the next 24 hours as he had a bit of delayed concussion with the knock," said the Spaniard.
"He was okay and then all of a sudden he became dizzy and he couldn't remember what was happening and we couldn't take any risks.
"He said he didn't remember he scored so I told him he scored from 40 yards!"
