Team's best offensive lineman anxious to play Sunday against Houston after missing past three games with a left knee sprain.
He still has to prove the left knee is sound, but Indianapolis Colts offensive left tackle Anthony Castonzo sounds like he's ready to re-join his teammates for Sunday's all-important AFC South Division clash against the Houston Texans at Lucas Oil Stadium.
Castonzo said Monday the original timetable for his return was last week against Jacksonville, a 51-16 road loss. So the Colts' best offensive lineman is even more anxious to play against the Texans, who have the same 6-7 record and share the division lead.
