Sadly this is probably an abandoned team. Maybe the manager has stopped playing or has lost internet connection. This has happened to me a while back, I lost my internet and I could not update my team for a few weeks. T11 has a policy of allowing 70 days for teams to be re-activated before deleting, to take into account unforseen circumstances for each player. It is unfortunate to come across abandoned teams but it is sadly just part of the game. T11 will try its best to make a game go ahead but if your opponents do no have 11 fit players then you get a 3-0 win.
