Cole Forbes impressed for Warriors

Tries from Cole Forbes, Fotu Lokotui, Fraser Brown and Kyle Steyn handed Warriors the bonus-point win with Edinburgh replying through Dave Cherry, Pierre Schoeman and Stuart McInally.

It was a bad-tempered affair with both teams making use of the new captain's challenge rule being trialled in the Rainbow Cup to successfully alert referee Adam Jones to red card offences, with Edinburgh's Mark Bennett and Warriors prop Oli Kebble sent off.

Ali Price - just a day after learning he would tour with the Lions - had a role in the opening try inside 15 minutes. With Glasgow already leading through a Ross Thompson penalty, Price's short-ball for Forbes caught Edinburgh completely by surprise as the full-back took a great line to dart through to score.

Indiscipline has dogged Warriors throughout the season and Fraser Brown's needless shove on Van der Merwe when Glasgow had already won a penalty proved costly.

Edinburgh kicked for field position in the Warriors 22 and they made the most of their opportunity as Cherry scored off a line-out maul.

Glasgow hit back straight away as Fotu Lokotui wriggled over, but when Warriors lock Robert Harley was sin-binned after repeated breakdown infringements, Schoeman was able to take advantage to squeeze over for another Edinburgh score.

Then came the TMO drama as Glasgow skipper Brown used the most of the new rules to alert the officials to Bennett's high hit on Price.

Harley was just making his way back on before the interval when Glasgow was back to 14 men as Edinburgh captain Grant Gilchrist complained about Kebble's elbow on Henry Pyrgos.

Brown crashed over between the posts for Glasgow's third on the stroke of half-time.

The rule experiment meant both sides were able to replace their dismissed players after a 20-minute period - but Glasgow had already chalked up the bonus point by then as Forbes' long pass found the unmarked Steyn to score in the corner.

Edinburgh hit back with their third as McInally broke off the back of a maul to score down the short side.

They were given late hope when Richie Gray was sin-binned as Warriors coughed up penalty after penalty. But McInally was denied his second by Ratu Tagive's last-gasp challenge.
