Penrith Panthers and Australian Kangaroos captain has been taken from the field before halftime during the club's clash with the New Zealand Warriors on Friday evening with concerns for a pectoral muscle injury. Yeo came reeling out of a tackle just five minutes before halftime, and replays seemed to show almost immediately the mecahnism of a pectoral muscle injury. After halftime, it was revealed the Panthers are fearful of either a pectoral muscle or shoulder injury. The Panthers will be sweating on the injury being something other than a major pectoral muscle injury, with hope it could be minor, or something else that has gone wrong. Pectoral muscle injuries have been on the rise in recent years in the NRL, with most clubs impacted at one point or another.
