Isaah Yeo’s NRL season appears in doubt after the Penrith co-captain suffered a suspected pectoral injury in a 28-12 loss to the Warriors that blows open the race for the minor premiership. “It doesn’t look great,” Panthers coach Ivan Cleary said of Yeo’s injury. “Obviously Yeoy’s a big loss and hard to replace, but that’s how it goes, if that’s the case, we’ll have to (replace him).” “The big news out of this first half is the injury to Isaah Yeo,” Michael Ennis said on Fox Sports. After Erin Clark waltzed over for a very soft opening try, Metcalf backed Kurt Capewell up and gave the hosts a 12-0 lead.
