Titans' Walker practices but remains questionable for Sunday (Yahoo Sports)

Tennessee Titans tight end Delanie Walker practiced Friday and is listed as questionable for Sunday's game at Houston due to a hamstring injury. The injury prevented Walker from playing in the Titans' last game, a 17-10 loss to the Oakland Raiders. ''I didn't even practice last Friday, so to be able to practice this Friday and make it through a whole practice, I feel there's a good opportunity that I can be playing Sunday,'' Walker said.
