Mychal Thompson: 'Klay Thompson sick following head injury'

Klay Thompson's father has revealed that the Golden State Warriors shooting guard was sick after suffering concussion-like symptoms following the team's Western Conference finals success.

Thompson was kneed in the head in the fourth quarter of the 104-90 win over the Houston Rockets earlier this week, and was cleared to return to the game immediately afterwards before developing symptoms.

Mychal Thompson, who won two NBA titles with the Los Angeles Lakers in the 1980s, told ESPN: "He threw up a lot late last night but he felt much better afterwards. Hopefully this break in the schedule will be a good break for Klay and the Warriors.

"That's what you feel like when you have a concussion. I had a few of those when I played back in the stone age of the NBA. We used to just play through them. But now the NBA is really careful with them."

The Warriors will face the Cleveland Cavaliers in the NBA Finals, which get underway next Thursday.
