Celtic manager Neil Lennon will introduce stricter rules for his players after Aberdeen were struck by coronavirus controversy.
The Dons' Scottish Premiership clash against St Johnstone has been postponed after two players caught Covid-19 and six others were instructed to self-isolate following a mass trip to a pub.
Asked about the limits on his own players, who face Kilmarnock tomorrow, Lennon said: "I know a few of them have been in restaurants and adhering to the protocols of said establishment. After what's happened, I think we will have to nip all that in the bud.
"If we want to extend the season then we will have to follow really strict guidelines and probably go back to the way it was before in terms of just training, then home, maybe walk to the shop, get provisions and go home again.
"Both in terms of the players and my staff and myself, we have to be really strict now."
Motherwell boss Stephen Robinson, whose men face Dundee United today, had sympathy for Aberdeen counterpart Derek McInnes.
"We test two or three times a week, we do more than any other people in society, more than the NHS, they are getting tested with symptoms, we constantly test and have protocols in place," he said.
"Unfortunately we can't control what people really do outside of football.
"We are trying our very best to control them but young boys go for coffee and things like that, it's very hard to control.
"I genuinely believe Scottish football is doing everything in its power to make sure protocols are followed. We remind them constantly, my messages are clear.
"There's going to be people testing positive throughout the season, there is no doubt about that, and we have to manage it."
Kilmarnock manager Alex Dyer held a meeting with his squad to remind them of their responsibilities.
"We get tested twice a week - but it's no good that happening and then the players going out in public mixing with other people who have not been tested," he added. "You have to be careful.
"When I addressed my players I told them they may be going out for a meal with their wives, which is nice. But not to a bar.
"You can't be going into public as a group. As young men going to a bar, you know what happens. You laugh, you joke, you drink. People come up to you."
