Some of Warren Gatland’s British & Irish Lions squad are in a race against time to be fit for the tour of South Africa.
#1. Dan Biggar (England)
Saints lost fly-half Biggar to concussion during the first half of the game against Gloucester last weekend.
The Wales star was involved in an unfortunate collision with Billy Twelvetrees and later failed a head injury assessment.
Chris Boyd said: "He's okay. He had that clash with Billy Twelvetrees and failed his HIA. He didn't seem to have any symptoms.
"We've got a bit of a longer week, not playing until next Monday (at Newcastle) so he's got plenty of time to hopefully recover."
