I'm afraid you've just been hit with the injury stick. I too had it at level 3 on an alt team. I ended up with 6 strikers just to get 1 on the park in Season 3.

It was very very annoying until it got so bad that it became funny.

On the plus side I ended up with 2 very good strikers out of that bunch.

All I'd say is don't spend tokens for kits. Its better to put up with injuries and field OOP than go down that road.
