Jonas diagnosed with flexion extension injury of the neck (whiplash)
The injury is akin to whiplash commonly suffered in an autoaccident. Except in this case, it was jonas' neck and shoulders being contorted by gay's shoulder.
Its not a major injury, especially considering the specialist/therapists available to the raptors. No info whether he'll come back with only a handful of games left. Knowing the raptors, he probably wont.
