South Africa winger Sbu Nkosi

Nkosi suffers ankle injury

Nkosi impressed in his first three international appearances during the Springboks' series win over England in June, scoring two tries.

The 22-year-old returned to Super Rugby action with the Sharks but the team confirmed on Thursday that Nkosi has suffered a syndesmosis sprain in his left ankle, leaving him doubtful for South Africa's next international outing.

Nkosi is expected to miss up to three months with the injury, with the Sharks hopeful he could be back in eight weeks.
