Centre Bundee Aki is poised to make his debut for Connacht after finishing with Counties Manulau and the Chiefs in New Zealand.
All-Black legend Mils Muliaina, who has been in Ireland since August and is recovering from an elbow injury, and hooker Tom McCartney are on target to make their debuts for Connacht against Zebre in three weeks.
But Aki will be the first of them into action tomorrow night as Connacht, with four wins and a draw from their opening six games, bid to bounce back from last weekend’s disappointing 33-13 loss away to Exeter in the Challenge Cup.
Lam rested several players last weekend for tomorrow night’s trip to play an Ospreys side who top the table with six straight wins.
Captain John Muldoon, impressive on-loan lock Quinn Roux, winger Matt Healy and back rower Eoin McKeon are all poised to return.
However, prop Ronan Loughney, who can play on both sides of the scrum, is out for two to three weeks with an ankle injury.
Lam said that he managed his squad to take the two away games into account.
“It is a difficult challenge because they are the best team and we are playing them in their home ground but ultimately for us that is exciting,” said Lam.
