Stuart Broad is hoping for good news as England await an update on the full extent of the injury suffered by James Anderson during the first Ashes Test.
England's leading Test wicket-taker Anderson had been deemed fit to start the series opener after suffering with a calf problem in recent weeks, but an issue with the same muscle saw him limited to just four overs on Thursday.
Broad, who picked up the slack with a superb five-for, revealed the veteran apologised for his inability to aid the cause.
But England are optimistic that a test on the "tight" calf would return positive results.
"[Anderson] went off straight after his spell but didn't say anything and came out back to field. We don't know the full extent yet," said Broad, in quotes reported by BBC Sport.
"He is a bit quiet and came up to the bowlers and said sorry but there is nothing to be sorry about. He is a bit quiet and bit frustrated.
"All we can hope is the news is better than we expect."
Figures of 5-86 included Broad's 100th Ashes wicket, removing the resolute Steve Smith after an outstanding 144 to close the Australia innings.
FIVE for @StuartBroad8!

Having seen the tourists recover from 122-8 to 284 all out, Broad acknowledged he had forgotten quite how exacting such rollercoaster contests can be in one of sport's greatest rivalries.
"I feel quite exhausted," he said. "I think that comes with the emotion of the first day of an Ashes series.
"You forget how emotionally draining these series can be and we went down to a three-man seam attack, which upped the overs.
"Smith played a wonderful knock, but anytime you bowl them out for under 300 on the first day of a Test match, we're pretty happy.
"It looks like there's runs out there if someone gets in, so we should take encouragement from the way he played.
"Australia threw it back at us after tea and I'd expect that throughout the series."Published 02 Aug 2019, 00:44 IST
