Richmond is still to decide whether key forward Ty Vickery will return after his four-week suspension, for this Saturday’s must-win clash against Sydney.

Vickery was in good form before his ban, and has continued to train strongly in the hope of returning for the final round of the home and away season.

His absence has allowed Griffiths to return to the team in support of star forward Jack Riewoldt, and has given coach Damien Hardwick a dilemma as the Tigers prepare to travel in search of their ninth straight win.

"We'll name a squad of 25 and probably make some choices over the next two days," Hardwick said on Thursday.

"It's going to be a tough decision ... (Vickery) is a very good player, (but) he hasn't played for four weeks.

"Whatever is best for us to win will happen. Whether it's playing Ty or not playing Ty, we've got to win."

Hardwick said the Tigers were drawing confidence from a number of factors ahead of their clash against the ladder leaders at ANZ Stadium, with a win guaranteeing them back-to-back finals appearances.

Star midfielder Dustin Martin will return after missing one match because of a minor hamstring strain, adding to a number of potential match-ups Hardwick said could be to the Tigers' advantage.

"There's certain match-ups that we think are favourable, and they've probably got the same from their point of view," he said.

"We won't go into those here and now, but we think we match up pretty well against them.

"We're both very good contested ball sides, we've both got forwards that are dangerous, but our defenders are quite capable also."

The most intriguing match-up is star Swan Lance Franklin against form defender Alex Rance after the pair had an entertaining battle at the MCG in round 14, with Franklin eventually breaking free to kick four goals in the Swans' 11-point win.

"It's one of the best match ups we saw this year; they had a truck load of one-on-one contests and 'Buddy' was the match-winner in the end," Hardwick said.

"I thought Alex handled himself really well in that contest.

"He's done it probably the last three or four times, so they have a great contest."
