Injury woes continue to get worse for the Giants as ruckman Rory Lobb will miss the next month of games with a back injury.

In the Giants' round 12 clash, Lobb was taken to hospital during the game and was cleared of any serious issues. The fear was Lobb may have punctured a lung.

Lobb was still in pain during the team's bye week and scans have revealed small fracture in his thoracic spine.

"The crack is really small but it's in one of those really awkward spots in his back," Leon Cameron told the media on Tuesday.

"We've got to be really careful that it doesn't turn into a bigger issue later in the year.

"It's really disappointing because Rory it was his fifth game back from his knee, and he was just starting to get some momentum, but unfortunately he's not going to be playing for four or five weeks. 

"He wants to get some continuity with the midfielders too, and that’s what we want as a club, but that’s what happens." 

The West Australian has been unfortunate with injuries all season. He battled a groin-issue in the pre-season and then missed four matches after suffering a bone bruising in his knee against Sydney in round three.

Dawson Simpson and youngster Matt Flynn are will battle replace Lobb this week against Brisbane.

It's not all bad news for the Giants however as vice-captain Stephen Coniglio (concussion) has been cleared and will take on the Lions this Saturday.
