Rugby:Johann Muller and Dan Tuohy are the main injury concerns following Ulster's disappointing defeat to Northampton in the Heineken Cup; a result they need to quickly put behind them and move onto this weekend's challenge against Leinster.

Muller sustained a soft tissue trauma to his right quad and will have ongoing treatment this week and management are hopeful he will be available for the crunch Magners League game against Leinster at the RDS on Saturday (kick-off 8pm).

Tuohy sustained a nasty facial injury to his right eye but both the x-ray and CT scans this morning have shown no bone damage.

Ulster are second in the Magners League standings with Leinster fourth as the shake-up to decide the four play-off places enters the final straight. Munster are still top with Ospreys third and with three Irish provinces surrounding them for company.
