BOULDER — The Travis Hunter Heisman Train could soon be getting back on track. Hunter, the Buffs’ two-way star, “should play, for certain” at Arizona on Saturday, coach Deion Sanders said during a news conference Tuesday. The junior cornerback/wide receiver left CU’s home loss to Kansas State last weekend after taking a hit to his upper body with 8:08 left in the second quarter. ESPN reported at the time that Hunter’s right shoulder was being examined.
