The Ravens remain optimistic that the hip injury sustained by Dennis Pitta early in preseason will not be season-ending as originally feared. Speaking with the media on Friday coach John Harbaugh said the Ravens are still considering whether to use the Injured Reserve-Designated-To-Return tag on Pitta. As it implies that designation -- which was used by Ray Lewis after his triceps injury last year -- would keep open the option of Pitta's return later this season. Pitta the Ravens' top tight end last season with 61 catches for 669 yards and seven touchdowns in the regular season -- went down early in camp with what was diagnosed as a fractured hip after he crashed to the ground in the end zone during practice. The injury was originally thought to be season-ending but Harbaugh said later that there was no ligament or cartilage damage so a return this season hasn't been ruled out. The Ravens opted to keep Pitta on the 53-man roster that was set on Saturday. That buys them a few more days to decide whether to place Pitta on the IR/Designated to Return list or whether to place him on regular injured reserve which would end his season.
