Injury blows for Ulster
McCall suffered a significant right hamstring injury and he will see a surgeon in London this week to explore surgical options. While Browne sustained a concussion. Both players will not be available for selection for Friday's sold-out game versus Connacht.
A number of other players picked up soft tissue knocks at Stade Marcel Michelin, but all of them are expected to be available for this week's fixture.
Andrew Trimble is available for selection once again after recovering from a foot injury he suffered while playing for Ireland versus Australia last month.
Ricky Lutton, Ross Kane, Alan O'Connor, John Donnan, Robbie Diack, Marcell Coetzee, Mattie Rea, Stuart Olding, Jared Payne, Craig Gilroy and Pete Nelson are still not available for selection.
