Gibbs extended his contract until the end of 2014 in February, but recent speculation had suggested he was keen to make a move.
The Tigers were allowing him to have contract talks with other clubs, but Humphreys suggested the 26-year-old was yet to decide if he wanted out.
“We’ve given permission to Bryce’s manager to have a chat to a couple of clubs, which was a request that came from him,” Humphreys said.
“There are no strong moves from him (Gibbs). I think there was some interest in him, so they did the right thing and spoke to us about it.
“Bryce has been a great servant of our club, so if there was something he wanted to pursue, then we wouldn’t want to get in the way of that.
“But he is also a great club man, so I’m not sure how that one will play out.”
