SHEFFIELD slipped to their heaviest defeat of the season as they went down 55-37 at Glasgow.
The Tigers never recovered from a slow start, which saw them concede heat advantages in all four of the opening races, and were able to register just four heat wins all night.
Despite losing Josh Bates earlier in the day through illness, team boss Simon Stead says being a man down had nothing to do with the result and offered no excuses for his side's performance.
"We've got a team full of riders who are more than capable of making up the points for rider replacement but tonight we definitely didn't do that," Stead said.
"That's probably the most disappointing performance and result we've had since I've been team manager and some members of the team have to go home tonight and think long and hard about things after a meeting like that.
"Don't get me wrong Glasgow are a very strong outfit this year, particularly at home, but with the team we've got we shouldn't be getting demolished like that.
"It's frustrating and disappointing and they're the two main emotions amongst us all right now I think.
"We simply weren't good enough tonight, we were beaten by a much better team and we need to learn some lessons from tonight going into the rest of the season."
Lasse Bjerre and Josh Grajczonek scored 26 of the Tigers' 37 points with the other four members of the team managing just 11 between them.
There is no action at Owlerton this Thursday; the Tigers head to Workington in the SGB Championship next Saturday (July 8).
