SYDNEY Swans coach Paul Roos says the club hasn't set a deadline for premiership defender Tadhg Kennelly to make a decision about resuming his AFL career.

The 28-year-old quit the Swans with a year remaining on his contract to return to Ireland and play Gaelic football.

Kennelly aimed to emulate his late father, Tim, by winning an All-Ireland medal with County Kerry - a feat he achieved in September on his first attempt.

As Kennelly was still contracted to the Swans for the 2009 season, the club can re-sign him without going through the NAB AFL Draft or Pre-Season Draft.

However, his contract must be submitted to the League by December 2 - the cut-off for clubs' third list lodgements and total player payment estimates for 2010.

Roos said he hadn’t spoken with Kennelly since the All-Ireland final but he was in no doubt that the dashing flanker knew what was required to continue his AFL career.

"Obviously he's been really busy with the book launch and the grand final and all that other stuff, so I haven't spoken to him," Roos said on Monday.

"But I think he's smart enough to know. He's got a manager over here who deals with a lot of other players and he'd be aware of that."

In an excerpt from his forthcoming book, published in the Irish Independent last week, Kennelly said he remained unsure about his future.

"[After the final] I described how my heart was with Kerry and how I felt I hadn't yet become all I could be as a Gaelic footballer," he wrote.

"All of this was true but the reality was I didn't know what I was going to do. There were so many factors to consider.

"My family, my life with Nicole, my financial future, my sense of unfinished business in Australia."
