Marika Koroibete and the Storm moved into the Auckland Nines semi-finals with a win over the Cowboys.

Storm winger Marika Koroibete has accepted a one-match suspension while Eels forward Manu Ma'u will challenge a dangerous contact charge at the judiciary on Wednesday night.

Eels forward Manu Ma'u and Storm winger Marika Koroibete are both facing suspension, two of three players cited by the NRL match review committee from Easter Monday's NRL Telstra Premiership fixtures.

Ma'u (grade one dangerous contact – head/neck) was charged for his 58th minute challenge on Wests Tigers forward Josh Aloiai, and a poor record will see him miss two matches if he is found guilty at the judiciary.

Koroibete was charged with tripping and will miss this week after accepting a one-match ban.

Newcastle's Nathan Ross was hit with a grade one dangerous contact charge but has escaped suspension with an early guilty plea.

From games earlier in Round 4, Titans forward Ryan James has pleaded not guilty to his dangerous contact charge and will face the NRL judiciary on Wednesday night.

Chase Stanley, Frank-Paul Nuuausala and Joel Thompson all elected to take the early guilty plea and will be free to play in Round 5.
