Smith retired hurt suffering concussion, but resumed his innings 40 minutes later, eventually getting out lbw. He is now in a race against time to be passed fit for the third Test starting at Headingley on Thursday. The former captain needs to train in Leeds and then face the teams back-up fast bowlers in the nets on Wednesday as well as pass concussion tests.
While the Australian Cape Town trio has been booed extensively during their British tour over the sandpaper scandal, Saturday's booing of Smith has been widely condemned, including by Mr Morrison who said it was a "total Ashes foul".
Britain's sports minister Nigel Adams said it was time for the booing to stop.
"The vast majority of the Lords crowd were on their feet applauding Steve Smith after his innings but a small amount of booing from a tiny element of the crowd has made the news," he said.
"Its distasteful and we have to remember that the Aussie players who got themselves into trouble have been punished and done the time.
"Smith, in particular, is a brilliant batsman and whilst of course, I dont want him getting too many runs while hes over here, hes mesmerising to watch and as genuine sports fans we should be applauding him, not jeering."
Adams, a cricket nut, is Secretary of the Lords and Commons Cricket Club and is a Lord's centurion, having scored 125 not out against the Marylebone Cricket Club (MCC) while captaining his side in 2014.
He was one of a string of prominent British and Australian politicians and figures to attend a reception for the Australian Men's Cricket team at the Australian High Commission last week.
Former bowler and Australian coach Jason "Dizzy" Gillespie said, while the boos were going to happen after the sandpaper incident, Saturday's were not only disappointing but also hypocritical.
"I think it has been disappointing to hear the boos when he was hit by Jofra and certainly when he came back out to bat," Gillespie said.
"There are some short memories within these shores – a number of players have been guilty of changing the condition of the ball – including English players – I dont believe they have been subjected to the same treatment Read More – Source
