Tano was sent for a scan to determine the extent of the damage to his injured ankle and the physios should have the results by Tuesday morning and are hopeful that the knock is not too serious.
The Argentinian wing-back collapsed in agony after a chase down the touchline in Sunday's Premiership win against Newcastle United.
'Tano' appeared to go over on his ankle himself - there was certainly no contact with a United player - and left the arena in some pain.
Glenn reported: "We're hoping it's not a bad ligament strain. He felt pain but we won't know until tomorrow.
"He'll have X-rays and we're keeping our fingers crossed that it's not as bad as we first thought.
"It will be a concern because with Stevie Carr out, Chris Perry played there and did well, but it's something I have to think about for the next game because it might change the shape of the team."
Glenn Hoddle will keep his fingers crossed for the results of Monday's scans on Mauricio Taricco's ankle injury.
