Cowboys forward Tariq Sims will join the Newcastle Knights at the end of the season on a two-year deal.

Tariq Sims suspended for two weeks

Cowboys enforcer Tariq Sims will sit on the sidelines for the next two weeks, including this Saturday's clash with the Storm in Townsville, after lodging an early guilty plea on a dangerous throw charge resulting from an incident in North Queensland's loss to the Raiders on Sunday.

Sims' suspension was a consequence of his lifting tackle on the Raiders' Shaun Fensom in the 36th minute of the clash in the nation's capital.

Meanwhile Broncos' back-rower Todd Lowrie is free to play against the Sea Eagles at Suncorp Stadium on Sunday after entering an early guilty plea on his high tackle charge, which came after a clumsy hit on Wests Tigers back-rower Bodene Thompson during Brisbane's close-fought win in Campbelltown.
