RANGERS’ boss Steven Gerrard has welcomed news that Hampden chiefs are to trial concussion substitutes in this season’s Scottish Cup as he confirmed that Leon Balogun will sit out Saturday’s clash with Motherwell after picking up a head knock.

The International Football Association Board (IFAB) this week gave the green light for emergency replacements to be tested, and the Scottish Football Association plans to introduce them at the “earliest possible opportunity.”

Asked if he welcomed the plans, Gerrard said: “Very much so...I certainly welcome the trials in terms of up here in Scotland. I know England are looking into doing the same things and the quicker we can move the better.

“Because I think we have to look after the welfare of the players, certainly when it comes to head injuries as there has been a lot of talk about situations later on in life that head injuries can lead to dementia and stuff.

“I certainly welcome developments in that area to improve the game and the welfare of the players as well.”
