A league source told Scout.com that Houston Texans starting DT Amobi Okoye (high ankle) will not dress for Sunday's game against the Baltimore Ravens. Okoye didn't practice Wednesday or Thursday.

With Okoye out this week, look for veteran DT Jeff Zgonina and rookie DT Frank Okam to fill in. Zgonina, who has started 65 games in his 16 seasons of play, is likely to get the start this week.

In other team news Thursday, starting SLB Zac Diles (broken leg) was placed on injured-reserve. LB Kevis Coley was signed off of the practice squad to take his place on the active roster.
