"Any opportunity we get to get in the middle is good, it got some of the competitive juices going though there are percentages to go up against first-class opposition.
"Jacques played well, it's nice for him, for the team and the supporters.
"The three injuries are being monitored day by day, it's unlikely all three will be fit for Northampton.
"We hope as many as possible of them will be fit, but if they're not, the players in those positions have had opportunities throughout pre-season."
