Walker is questionable for Friday's game against the Bucks due to an illness.
The Pacers are depleted in terms of their wing depth, and the potential absence of Walker doesn't help the team's cause. Andrew Nembhard (knee) and Aaron Nesmith (ankle) are out, while Ben Sheppard (oblique) is questionable as well. Quenton Jackson would be in line to start if both Walker and Sheppard are sidelined.
