Aside from Machida, the only relatively top LHW available for Goose, depending on the timeline return from injury is Bader, and I'm not too certain if he'll be ready any time soon.
Goose could be a replacement for Hendo/Evans or Te Huna/Texeira if an injury occurred, but outside of Machida, if he wants to fight soon-ish, LHWs of note he could be paired up with aren't really at his ranking level, such as Manuwa or Hamill, which would be majorly risky for Goose....
