- The Sharks are sweating over the availability of two Springboks, Curwin Bosch and Bongi Mbonambi, for their Champions Cup clash with Harlequins next weekend.
- Bosch didn't even make the match-day 23 in the Sharks' 32-3 victory over French club Union Bordeaux-Begles at Kings Park on Saturday.
- Mbonambi, meanwhile, left the field early after suffering a shoulder injury in the Sharks' dominant win at home.
The Sharks are holding their breath over injuries to Springboks Curwin Bosch and Bongi Mbonambi, who are doubts for their trip to London to face Harlequins in the Champions Cup next weekend.
Hooker Mbonambi had to be substituted early in the game after hurting his shoulder in contact while carrying and was replaced by Kerron van Vuuren in the Sharks' 32-3 victory over French club Union Bordeaux-Begles at Kings Park on Saturday.
Flyhalf Bosch didn't even make it onto the field and was replaced by Lionel Cronje at pivot, which opened up space on the bench for Springbok Aphelele Fassi to return after suffering an ankle injury during the SA A tour of Europe last year.
Sharks director of rugby Neil Powell said Bosch, who was injured for the opening eight rounds of the United Rugby Championship (URC), came into the matchday squad with a hamstring issue and they didn't want to risk aggravating it.
"He (Bosch) picked up a bit of a hammy during a performance session on Thursday and we were hoping he would pull through during the captain's run on Friday.
"Unfortunately, he didn't and we didn't want to risk him. The physios are confident that he will be back next weekend but it's a case of, do we want to risk him or wait for him to recover fully before we get him back onto the field?
"So, the positive is that we'll have a bit of time before we depart for London to play Harlequins, so hopefully we can do a proper assessment of all our injuries before we get onto the plane."
Bosch had shown good form since returning from injury, playing under Powell, who seemed to have reignited the Sharks prodigy.
Mbonambi was one of the big guns that were rested last weekend for the URC trip to Connacht but hardly made 10 minutes on the park in Durban.
If missing, he'll be a big loss for a Sharks side looking to seal a high Pool A finish to ensure a home passage throughout the Champions Cup knockout stages and to the final in Dublin on 20 May.
"We're going to assess Bongi on Monday. I'm not the medical doctor, so he will do the assessment of all the players, send them for scans if need be.
"We'll make a decision based on that. I can only say it's a shoulder injury and hopefully he'll recover in time to be ready again for the Harlequins game."
