NRL to investigate Storm complaints

The NRL will today investigate Melbourne's complaints about the Wests Tigers following the Storm's win over the joint venture club at Olympic Park on Saturday night.

The Storm are upset about the amount of time Tigers trainer Andrew Leeds spent on the field and have questioned the legality of winger Pat Richards' kicking tee.

Meanwhile, lock Dallas Johnson has been rated a 50-50 chance of returning from a knee injury for the Storm's clash with North Queensland in Townsville on Saturday night.
