Gary Kubiak has confirmed that DeAndre Hopkins was diagnosed with a concussion during the Houston Texans' pre-season win over the Miami Dolphins last night.

The wide receiver, who was selected by the Texans in the first round of this year's draft, left the game in the second quarter after taking a knee to the helmet.

Speaking to reporters after the game, the head coach said: "He got a concussion. I don't know exactly what play it happened on, but I thought something was wrong. He seemed a little woozy. I told [wide receivers coach] Larry [Kirksey] to get him out of there and then we checked him out.

"He's fine now, he's doing fine, but we're obviously going to put him through the protocol. I think it happened on the first or second ball that he caught in the game, I think.

"I just know that we ran another play actually on the interception, and he looked like his legs went out from under him. He just didn't run the route, didn't get his depth, stumbling all over the place. I told Larry to check on him and then we got him out."

Hopkins scored his first NFL touchdown last week during the Texans' pre-season win over the Minnesota Vikings.
