Celtic manager Brendan Rodgers has claimed that too many bad tackles are being allowed in recent Scottish Premiership matches.
The former Liverpool and Swansea boss was unhappy with a challenge on Celtic's young left back Kieran Tierney by Motherwell's Ryan Bowman last weekend as well as challenges in other games before that.
The most recent incident resulted in a yellow card.
Rodgers has called for stricter refereeing to protect players.
"The concern for me is the ones that are late, the one like last week that was a straight leg challenge that could have really damaged him," he said.
"That's the duty of the referee, to protect the players, and the game.
"I've seen two tackles in the last two games that weren't good tackles at all. The tackle on Kieran Tierney was horrendous. This is a kid who's coming through, he's 19, one of the great prospects of Scottish football. I've a boy who's a brilliant coach on my staff, John Kennedy, who was also a brilliant prospect who in one challenge lost his career."
Rodgers has guided Celtic to the brink of the Scottish league title in his first season in charge.
The Hoops are already 24 points clear of second placed Aberdeen with just 13 matches of the season to go, with the title virtually secured already.
Last season, the league was won by 15 points which highlights the scale of Celtic's improvement under Rodgers.
