Neil Lennon has urged Leigh Griffiths' critics to start showing the Celtic striker some compassion.

The Hoops boss confirmed his club have written to Sky Sports to lodge a complaint over comments made by pundit and former Rangers striker Kris Boyd following Wednesday's win at Kilmarnock.

Boyd went on the attack, claiming Griffiths - who has recently returned to action following a battle with off-field demons - had struggled to meet the professional standards introduced during Brendan Rodgers' Celtic reign.

But that has upset the Parkhead hierarchy.

"I support the club and I think a little more discretion or tact could be used at times," said Lennon.

"We want Leigh to flourish now and to be happy. He's got plenty of mental strength otherwise he wouldn't have been here at the club for so long.

"I don't think people these days give much thought [what they are saying]. We live in an age now where there's no accountability or responsibility at times, whether it's a mental health issue or another issue.

"It would be nice if they showed him a wee bit more compassion at times. At the end of the day he's a human being."

Lennon confirmed youngster Jeremie Frimpong will sit out Saturday's visit of Ross County as he continues to recover from Alan Power's tackle in midweek.

The Dutch right-back was taken off on a stretcher after being sent flying by Power's lunge and the Hoops boss insisted the Killie man was lucky to escape punishment.

"Jeremie won't be fit for tomorrow," he said. "He's had a scan and we're just waiting on the results.

"We don't think it's as bad as we anticipated. He's up walking about on it but there's a bit of soreness. We just don't know the complete diagnosis yet.

"Jeremie is desperate to get back as quickly as possible. He felt very aggrieved after the game. He's that type of personality that means we'll see him sooner rather than later.

"I thought the tackle was overly aggressive and it could easily have been a red card. We've seen reds given for that."
