The Wales international has been out since May after having shoulder surgery but could return this Sunday at the Liberty Stadium.
And Tandy says the flanker is a huge influence on the rest of his side.
"It will be a good boost for us," Tandy told Wales Online.
"We would have liked to have him in the mix for the Dragons game, but we gave him a little bit extra.
"He has come through the early part of the week in training. We have another contact session to come, so we will see how he pulls up after that.
"With someone like Tips, we know he will be able to get back up and running pretty quickly. If he comes through fit, there's potential he could start the game.
"We do need a specialist seven back, in terms of those natural instincts of a seven getting steals and getting on the end of some of those line-breaks. Natural sevens sniff out opportunities."
