When does Walker, Texas Ranger return?

The series was inspired by the film Lone Wolf McQuade, starring Chuck Norris as a member of the Texas Ranger Division. The show aired on CBS in the spring of 1993, with the first season consisting of three pilot episodes. Eight full seasons followed with new episodes airing from September 25, 1993, to May 19, 2001. It has been broadcast in over 100 countries and spawned a 2005 television film entitled Trial by Fire.
The show is centered on Sergeant Cordell Walker (Norris), a Dallas–Fort Worth–based member of the Texas Rangers. Walker was raised by his paternal uncle, an American Indian named Ray Firewalker. The series was well known during its run for its product placement deal with Chrysler, especially its Dodge division.
