The Indianapolis Colts face the prospect of being without Bob Sanders – again – Sunday when they entertain the Houston Texans at Lucas Oil Stadium.

The veteran safety missed his second consecutive practice Thursday because of an elbow injury suffered in last Sunday’s win over the San Francisco 49ers.
“He’s getting it evaluated,’’ coach Jim Caldwell said of Sanders prior to this afternoon’s practice.

Caldwell added the injury did not keep Sanders from finishing the 49ers game, but it flared up “a little while later.’’

Sanders, the 2007 NFL Defensive Player of the Year, missed the first five games this season while completing his rehabilitation from offseason surgery on his right knee.

If Sanders misses the Houston game, Melvin Bullitt returns to the starting lineup.
Caldwell also was unable to provide an update on wide receiver Anthony Gonzalez, who sought a second medical opinion on an injury to his right knee. Gonzalez has not played or practiced since injuring his knee in the season opener.
