Livingston manager Paul Lambert has performed a U-turn and re-registered as a player following his side's poor start to the season.
Paul Lambert retired at the end of last season
The 36-year-old had taken charge during the summer saying that he could never imagine playing for any other club than previous outfit Celtic.
But he is set to play in a closed-doors friendly against Rangers on Tuesday.
"I've registered and we'll see how I feel later on," he said. "I trained last week and I feel okay."
Lambert had retired from playing saying that he could not stomach playing against Celtic, the club with whom he spent that last eight years after arriving from Borussia Dortmund.
But Livingston sit bottom of the Scottish Premier League after three opening defeats.
The former Scotland midfielder had hinted after Saturday's loss to Hibernian that he was considering playing again and is now suggesting that he is thinking of himself as cover for his squad.
"But it's not about me, it's about the boys that go out on the pitch," he said. "They're the most important ones.
"We'll have to wait and see what happens with injuries and suspensions and things like that."
