Smith will miss this week�s vital encounter after entering an early guilty plea for a grade one dangerous throw on New Zealand�s Jerry Seu Seu from last week�s two-point win over the Warriors.
However, in a bid to take his place in this week�s starting line-up, Sargent along with Storm assistant coach Dean Lance will contest the same charge relating to the same tackle at the NRL judiciary tomorrow night.
After beating a dangerous throw charge earlier in the year Smith will be sidelined for one week however if Sargent is found guilty he stands to miss three matches.
Last week�s eighteenth man Nathan Friend has been elevated to the role of starting hooker to cover the loss of 20-year-old Smith.
With a win this weekend almost certainly securing a finals berth for the Storm � Melbourne has a bye in round 25 and two home games yet to come � Lance is disappointed to have lost Smith but is confident the Sargent can beat the charge levelled at him.
�We�re defending Mitch (Sargent) because we think he isn�t guilty of a throw,� Lance explained.
�We think he�s the third party in the tackle and he was just hanging on to the player that was already in the action of being lifted by Cameron (Smith).
�As soon as he saw that the tackle was going above the horizontal he let go and was not party to it at all.�
Lance isn�t underestimating the importance of keeping intact the front-row that has seen the Storm climb to sixth position on the NRL ladder with just five rounds remaining.
�Sargent is important for us considering the injuries to some of our younger players from (feeder club) Brisbane Norths, we haven�t got the depth that we would have hoped for,� the former Leeds coach said.
�Everyone is important to us including Smith, but we need a front-rower in our side.�
The Storm will be looking to arrest a three-year losing streak when it takes on the fourth placed Bulldogs this Sunday.
