Hawthorn needs to use every minute it has to pick the right team to take on Port Adelaide on Thursday night, with coach Alastair Clarkson cagey on selection as the team flew out of Melbourne Airport on Wednesday.

The Hawks are weighing up a number of selection moves as they travel for the second straight week on a six-day break, with young forward Tim O'Brien available after missing two matches with a hip complaint.

"We'll select our side tonight and we'll take a group over there and pick what we think is going to be the best side to take on Port," the coach said. 

"We'll reveal that at five o'clock this afternoon like everyone else does. We're not going to reveal anything now on the way we're going to select our side."
