X-rays on Colts RB Zack Moss' right arm came back clean, according to NFL Network's Mike Garafolo. Moss was having trouble gripping the football, per Garafolo, which is why he was unable to return to Saturday's win over the Steelers. RB Jonathan Taylor (thumb) also has a chance to return for Week 16. If both Moss and Taylor are out, Indianapolis would be down to RBs Trey Sermon and Tyler Goodson.
