Span unsure if he will return to Twins

Minnesota Twins outfielder Denard Span says the dizziness still ''comes and goes'' and he has a lower energy level from a concussion suffered June 3 and is unsure if he will return this season. Span, who is taking batting practice and doing on-the-field drills, said Wednesday he would like to play in a few games before the season ends to ''build some confidence'' going into the offseason. Span did return for nine games in early August, but went back on the disabled list with migraine symptoms. He has been limited to 65 games and is hitting .263. He was injured in a collision at the plate with catcher Brayan Pena at Kansas City.
