Jaco Kriel is the latest loose forward to join a lengthy injury list that includes Warren Whiteley and Duane Vermeulen.
Jean-Luc Du Preez replaced Kriel for last weekend’s clash with the All Blacks and is expected to continue in the role. With Cheetahs flank Oupa Mohoje appearing to be surplus to requirements, Louw could be next in line to come off the bench.
The 32-year-old Louw, who has won 52 caps for the Springboks, was a mainstay for the Springboks under the reign of Heyneke Meyer and has proven himself to be a stealthy fetcher, securing the second most turnovers at the 2015 Rugby World Cup.
If selected, Louw would miss the trip to last season’s Premiership table-toppers Wasps and probably Worcester Warriors the following week. Bath are also struggling with loose forward injuries and losing Louw for a few games could prove costly.
“I am on standby (for South Africa),” Louw told the Bath Chronicle.
“Whether or not they decide to use me, obviously there’s been a couple of injuries, but I think they’ve got enough good men there to do a good job.
“I’m obviously torn, as I’ve always been, whether I’m playing there or playing here.
“It’s a huge honour to play for your country. Any player who has represented their country can tell you that, but this is my club and a team I’m obviously very passionate about.
“This is my seventh season here. It’s great to be starting (the Premiership) with the guys, it’s something I haven’t experienced in the past.”
In an interview with SuperSport, Springboks head coach Allister Coetzee said: “The fetching role is quite crucial.
