Players who get extended time away from the club & mainly attending to injuries or personal life issues.
That could be anything from a ill family member, A new baby, Injuries that require complete rest, weddings, friends weddings, home sickness, Death of family member or friend, Time out because they have spent time around a sick child in hospital with terminal illness which most do. Holiday, Moving or Building a house. Whatever, the club allows many things. We only guess unless we know them personally. As long as they come back to work & give 100% that is all that counts.
