DEFENDER Sam Gilbert is expected to miss round one of the AFL season with a foot injury.

The left footer played six senior games in 2014 and has notched 146 for the Saints since his debut in 2006.

GM of Football Performance Jamie Cox confirmed Gilbert would miss at least the first week.

“In taking a cautious approach, there has been a revision of Sam’s rehab program, such that his running progression has been extended over a longer period. The fifth metatarsal stress fracture currently appears to be healing well,” Cox told SAINTS.com.au.

“However, Sam is experiencing heel pain in the same foot which will delay his physical preparation. It is now planned that he will return to training in late March and playing in late April.”

Joining Gilbert on the sidelines will be Arryn Siposs, the 22-year-old having undergone shoulder surgery in December after injuring it Queenstown, New Zealand.

“Arryn’s rehab will be continuing over the next four months and planned return to full training is in May,” Cox said.

The long-kicking forward registered three senior games in 2014 and has tallied 28 for his career.

He was a NAB Rising Star nominee in 2012.
