Walker is not part of the starting lineup for Monday's game against Houston.
The Pacers are going with a bit more size Monday to help counter a big Rockets frontcourt, deploying Jay Huff in the first unit. Across his last six appearances off the bench, Walker has averaged 11.3 points, 4.3 rebounds, 2.3 assists and 1.2 steals in 24.2 minutes per game.
