Klay Thompson showing “concussion-like symptoms” following knee to head By Kurt HelinMay 28, 2015, 2:55 AM EDT Share this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on Flipboard (Opens in new window)Click to share on Reddit (Opens in new window)Click to email this to a friend (Opens in new window) 26 Comments This is where the week off until the Finals tip off benefits the Warriors.It looked nasty when Klay Thompson was kneed in the head by Trevor Ariza in the fourth quarter (is there any time a knee to the head doesn’t look nasty). When it first happened, the team was more concerned about the cut on Thompson’s ear.Then that changed, the team said in a statement, via Monte Poole of CSNBayArea.com.“Klay Thompson was evaluated by the Warriors medical staff immediately after suffering an injury during tonight’s game and was put through a concussion evaluation. At the time he did not show any concussion-like symptoms. After the game he began to not feel well and developed concussion-like symptoms. He will continue to be evaluated by the team’s medical staff tonight.”To get back on the court now, Thompson will have to pass the league’s protocol. That involves him passing a series of tests (against a baseline taken before the season started), doing so through increased physical activity. This is overseen by the league’s neurologist.How long recovery takes varies with the severity of the injury and the player. That said with the Finals a week away expect him to play .
