QPR boss Harry Redknapp has called on the football authorities to consider following their rugby counterparts by allowing temporary substitutions to improve the treatment of concussion, reports BBC Sport. Redknapp was frustrated after medics withdrew Sandro just 11 minutes into Saturday's 2-1 defeat at Southampton following a heavy blow to his head.
According to Redknapp, the midfielder seemed to have recovered by half-time.
Redknapp said short-term replacements was an idea "worth looking at".
However, brain injury association Headway has warned that such a move could be dangerous.
