Williams injury fear
Nick Williams could have played his final game for Ulster as he battles shoulder and groin problems ahead of their crucial Guinness Pro12 run-in.
Williams was crocked during the team's collapse away to Glasgow as their playoff hopes took a tumble before the visit of Connacht.
Williams, who joins Cardiff next season, has only been officially ruled out for this week's game but his extreme discomfort may hint at a longer lay-off.
Irish trio Andrew Trimble, Rory Best and Jared Payne, who were ruled out with purportedly "low grade" injuries, will return this week.
However, second-row Alan O'Connor is another who could have played his last game unless Ulster recover their slipshod form and re-establish their playoff credentials.
He dislocated his right shoulder while playing against Glasgow and will see a shoulder specialist later this week to determine whether the injury will require surgery.
