GLASGOW must overcome a 12-point deficit to make it to the next round of the KO Cup.
The Tigers went down 51-39 away to Redcar tonight in the first leg of the fixture.
The away side were hurt by their lack of heat wins with only Craig Cook and Paul Starke putting three points on the board.
Boss Cami Brown will be frustrated given his side led by four points after just five heats before the Bears turned things around three 5-1s in four races.
The Tigers now head to Birmingham on league duty tomorrow before hosting the second leg against Redcar on Friday.
