Queens Park Rangers manager Harry Redknapp has said that temporary substitutions should be allowed to help deal with injuries to players.
Sandro was taken off during QPR's defeat at Southampton this weekend following a head injury, but Redknapp believes that a short-term replacement would have been ideal in the situation.
"You couldn't wait 10 or 15 minutes with 10 men; you couldn't give medics that amount of time to look at a player," BBC Sport quotes him as saying. "But it doesn't sound the worst idea for a temporary replacement, so that the doctors could have a longer look.
"Medical people can't take a chance and if someone is very bad you cannot expect them to carry on because if something went wrong we would all be very sorry.
"But at half-time there didn't seem to be a lot wrong with Sandro to me. He was fine in the changing rooms, he didn't look too bad at all but obviously the doctors have got to err on the side of caution."
QPR are currently 18th in the Premier League table.
