YOUNG St Kilda defender Hugh Goddard will spend the night in a Sunshine Coast hospital after suffering from heat stroke on Monday.

Goddard was rushed to hospital in an ambulance from the Maroochydore Multisport Complex after collapsing to the ground following a taxing running session.

St Kilda officials were quickly by his side with water, cold towels and bags of ice, before the 19-year-old was then injected with an intravenous saline drip from paramedics.

Goddard is now doing well but will be kept in hospital overnight to monitor his condition.

"Hugh pushed himself probably a little too hard," general manager of football performance Jamie Cox said.

"He suffered the effects of the sun and he has had to be taken to hospital just to be monitored.

"We can fortunately say he is going OK. He will stay in tonight but he's doing really well, which is pleasing."

It was day two of the club's pre-season training camp on Queensland's Sunshine Coast after they arrived on Sunday.

Goddard, a second-year defender, was running strongly until the final couple of one-minute efforts where he began to stagger in the stifling humidity.

After two years of pre-season training at Arizona's altitude and then another two in New Zealand, St Kilda has joined the growing trend of teams heading to the Sunshine Coast – 110km north of Brisbane.

Cox said Goddard would have no lasting effects from the heat exhaustion.
