St Kilda will consider surgery to clean up scar tissue in Nathan Freeman's hamstring after the luckless midfielder suffered yet another injury blow.

Freeman tore his hamstring at training on Friday, denting his hopes of breaking through for a maiden AFL game early in the season.

The 22-year-old, who was drafted in 2013, is in the final season of a three-year deal with the Saints, having been traded from Collingwood at the end of 2015.

St Kilda coach Alan Richardon had recently said that the top-10 draft pick was firming to play in round one.
