Celtic League Preview Glasgow v UlsterAfter single-handedly salvaging a draw against Leinster when introduced as a second-half replacement last Friday, it's no surprise David Humphreys is handed back the number 10 jersey for this evening's trip to Firhill.

The 36-year-old remains a crucial piece of the Ulster puzzle. Paddy Wallace is consigned to the bench with the power of Scottish international Rob Dewey preferred at inside centre. Justin Harrison returns to the secondrow in place of Italy international Carlo del Fava, as coach Mark McCall attempts to retrieve an increasingly desperate situation.

Ulster are bottom of the Magners Celtic League with six points from five outings. With Gloucester due in Ravenhill next Friday a rediscovery of some semblance of form is a must tonight.

The balance of the team looks fine. Foreign players have been recruited for problematic positions, the quality coming from underage continues unabated, as winger Mark McCrea has proved in recent weeks, so the coaching staff may come under the most intense scrutiny if results don't drastically improve.

Ulster have their best chance in years to reach the knock-out stages of the European Cup. The season starts here.
