Tano took a knock to his ankle in the first half and was offered the chance to withdraw at the break, but he gallantly played on and earned Glenn's admiration.
"I've got to say Tano did excellent for us, fantastic, he really did," said Glenn. "He played on when he might have been looking to come off at half-time.
"He said he'd try it and he played on in pain and played right through. Even in the end I was saying 'do you need to come off?' - he put his thumb up and said no.
"The bottom line is that he showed the character and spirit of the club.
"I think he's got a 50-50 chance for Saturday, but that's the sort of character that we need if we're going to achieve anything.
"No one would of known he had an injury the way he played in that second half, he got it 12 minutes into the game. Whether that's going to go against us this week remains to be seen.
"We've had scans done and it's not a massive damage to the ligament, it's more on the capsule and he has a chance of healing quite quickly."
With Steffen Iversen and Stephen Clemence stepping up their work after lengthy lay-offs, things are certainly looking up on the injury front.
"Tano is the only injury problem we've had since last weekend," confirmed Glenn.
Mauricio Taricco is doubtful for Saturday's trip to West Ham after battling on with an ankle injury sustained early in last week's clash with Arsenal.
