Edinburgh Rugby coach Alan Solomons rued injuries to Dougie Fife and Mike Coman as he sought to rationalise a damaging 3-9 defeat by Ulster at Murrayfield.
New internationalist Fife left the pitch at half-time with a hand problem while skipper Coman was withdrawn after taking a blow to the neck.
Also of concern to Solomons was a penalty count of 4-16 against Edinburgh.
“There was nothing between the sides and, in the first half, we had field position whereas in the second half they had field position.
“That sort of penalty count, though, is always going to make difficulties.
“We will spend time now with the SRU referee performance manager to get his input and it would not be appropriate to comment.”
Penalties have been a constant concern for Scottish teams all season and undoubtedly it was a major factor. But Solomons saw positives in the way Edinburgh stood toe-to-toe with Ulster.
“Ulster are certainly in the top three of Europe,” he said.
“Last year, they reached the finals of the Pro 12 and Heineken Cup and, when Andrew Trimble dropped out, they were able to bring in Tommy Bowe as part of a powerful sideand there was not much between the teams.”
One bonus for Edinburgh was being able to give a debut to Ewan McQuillin from off the bench in the closing stages and it was confirmed that the prop would still be able to turn out today for Gala when they bid to clinch a Scottish Premiership title at home to Ayr.
