New York Giants rookie wide receiver Malik Nabers is making progress despite being scheduled to sit out practice on Thursday, head coach Brian Daboll told reporters. Nabers remains in concussion protocol as New York continue its preparations for a road game against Seattle. The Giants (1-3) will travel to the Emerald City on Saturday morning, one day ahead of their game versus the Seahawks (3-1). Daboll said the team will wait as long as possible before making an official decision on Nabers. Also on Thursday, Daboll said running back Devin Singletary (groin) would not participate in practice while cornerbacks Adoree' Jackson and Dru Phillips would be limited due to their respective calf injuries.
