Paddy McCartin will miss the Saints’ trip to Perth, while Josh Bruce and Darren Minchington have overcome some major hurdles in their rehab programs.

McCartin sat out the latter stages of Sunday’s clash with Melbourne after a second knock during the game saw the key forward develop some mild “fogginess”.

The 22-year-old successfully passed a concussion test at halftime after an earlier clash of heads with Melbourne’s Neville Jetta.

St Kilda’s Head Physiotherapist Andrew Wallis tonight confirmed McCartin wouldn’t be selected to face Fremantle at Optus Stadium on Saturday night with the club keen to take all precautions with the young forward.

“The second knock left him feeling a bit nauseous and a bit foggy, and given it was late in the game, we took a conservative approach,” Wallis said.

“With the travel to Perth, he’ll miss this week and then we’ll update fans later.”

In good news for Saints fans, Darren Minchington has completed two one-on-one skills sessions and returned to training, with his expected recovery timeframe now just two weeks.

Key forward Josh Bruce has also shown promising signs, completing two running sessions with no pain in his back, and at this stage, the big man is expected to be available in four weeks.
