While Bryan Rodney struggled at times with Syracuse before being traded in a deal that sent Ryan O'Marra to the Anaheim organization, he's been solid for the Barons.
Rodney was minus-11 in 41 games for Syracuse but is plus-9 in 26 games for OKC since the trade.
Helmer, Plante, Rodney and Teubert will play in the postseason opener. Dan Ringwald played for the first time since Feb. 25 in the regular-season finale Sunday at San Antonio.
If Chorney isn't ready to go, rookie Martin Marincin figures to get the call.
In six games since signing an amateur tryout contract following the end of his junior season, Marincin is plus-4 and has shown flashes of why the Oilers made him their second-round pick in 2010.
