Ball has missed four straight games with a foot injury and is likely to miss the season finale on Sunday after once again missing practice.
Defensive tackle Shaun Cody (back), tight end Daniel Owens (hamstring/neck), linebacker Tim Dobbins (shoulder), tackle Derek Newton (knee), linebacker Brooks Reed (groin), defensive end Antonio Smith (ankle), and guard Wade Smith (knee) were all limited in practice.
Arian Foster (arrhythmia) and safety Eddie Pleasant (hamstring) were the only newcomers to the injury list this week, with both having full participation in practice on Wednesday. All other players were listed as probable for last week's game, with Alan Ball, Antoine Caldwell, Quintin Demps, Andrew Gardner, Terrell McClain, Stanford Routt and Cody White inactive against the Vikings.
The Colts and Texans kick off at noon on Sunday, with coverage on CBS.
