Brisbane: Australian paceman Jason Gillespie will be treated overnight for a tight calf muscle which restricted him to bowling just three overs against England in the Ashes cricket Test on Friday.

Gillespie has a history of injury-interruptions and had been struggling to be fit for the Test after tearing the calf playing for Australia against Pakistan in Sri Lanka early last month.

But team physio Errol Alcott said it was not the same injury, which forced Gillespie, 27, home early from the Pakistan series.

"He's concerned about the tightness in the calf, but its not the area that he tore, it's not his calf muscle, it's associated soft tissue," Alcott said after play on the second day on Friday.

Gillespie will be forced to prove his fitness in the nets on Saturday morning before being given the green light to bowl.

"You have to weigh up the situation and if we think he's got a serious problem then we'll have to think about what's best for him," Alcott said.

"At this stage, he's functional and he can field ... and I'm pretty confident but the human body, being what it is, means we'll have to see how he pulls up tomorrow morning after eight hours of not moving.

"He'll definitely have to bowl (in the nets) before he goes out if he wants to bowl tomorrow." Alcott said Gillespie jolted his ankle while batting and then felt tightness in his calf after bowling.
