This is about the last thing Dwyane Wade wants to worry about as his farewell tour continues toward the All-Star game. The Miami Heat legend was forced to leave his team's game against the Sacramento Kings on Friday night late in the first quarter after his head hit the floor while fighting for an offensive rebound.

Yikes. There's nothing scarier than when an airborne player loses control of his body, falls parallel to the floor, and is unable to brace himself. You can see Wade's head hit the hardwood and immediately bounce back off of it, a potential sign of a concussion or spinal injury. Fortunately, the future Hall of Famer was able to walk off the floor under his own power, as a partisan crowd at Sacramento's Golden 1 Center gave him a hearty round of applause.

Even more encouraging? Wade not only passed the concussion protocol without incident but returned to the action with 4:35 remaining in the second quarter.

Wade, 37, is playing his final NBA season before retiring. Along with the Dallas Mavericks' Dirk Nowitzki, he was named as a special selection to the All-Star game by commissioner Adam Silver, marking the 13th time he will appear in the league's midseason showcase.
