INDIANAPOLIS (AP) -Colts receiver Anthony Gonzalez is almost ready to return to action.

Gonzalez has been out since spraining ligaments in his right knee during a season-opening 14-12 victory over Jacksonville, and he has not practiced since. Gonzalez was primed to take over the No. 2 receiving spot after Marvin Harrison was released in the offseason, but the non-contact injury derailed those plans.

Coach Jim Caldwell said Thursday that Gonzalez is feeling good, and he could practice this week.

Safety Bob Sanders is expected make his season debut this Sunday at St. Louis. Cornerback Marlin Jackson is not expected back for at least two more weeks after straining the ACL in his right knee. Kicker Adam Vinatieri is out with a knee injury.
