Gold Coast small defender Connor Budarick and veteran Sean Lemmens have put their hands up for selection for Sunday's encounter against a struggling Carlton outfit at the MCG.

Budarick, a reliable defender, has had a wretched injury run, with two ACL tears in two consecutive seasons limiting him to only 11 appearances in the red, gold, and blue.

After getting through the final stages of his rehabilitation, the 21-year-old is all but firming for his first game since Round 16 last year.

"Connor has trained really strongly with the group over the last month, he's ticked all his markers and will be available to play this weekend," Suns Head Physiotherapist Lindsay Bull told the club's website.

"He's made every post a winner in his rehab and has attacked everything and worked really hard.

"We couldn't be more pleased with how he is - he's super confident, he's been training really well and has ticked his markers so we're really proud of him."

Like Budarick, Lemmens is available after recovering from a hamstring injury sustained during the side's QClash defeat to Brisbane in Round 10.

Meanwhile, former first-round selection Lachie Weller is still another two to three weeks from returning as he manages swelling in his knee, which has kept him on the sidelines since the Round 7 win over Richmond.

Co-captain and classy midfielder Touk Miller, who hasn't played since the North Melbourne win in Round 6, is another month away from returning from a meniscus injury.

The soaring Suns currently sit 12th on the ladder (6-6), only a game behind the seventh-placed Adelaide and the eighth-placed Western Bulldogs, having won five of their last seven.
