Baron, who played six times for South Africa, was injured in the first match of the league season away against Free State Stars when Wits lost 2-0 and has not played since.
His injury, combined with a similar long term lay off for second choice Jackson Mabokgwane, meant that Wits had to turn to teenager Hoffman to fill the gap.
The youngest goalkeeper in Premier Soccer League history has proven a revelation this season and is comfortably now the team’s first choice, even though Wits have since signed English-born Ryan Harrison from Santos as further cover in the goalkeeping department.
The 33-year-old Baron has had back and knee problems but is now back at training, Wits officials said.
He joined Wits last season on a free transfer after being booted out by SuperSport United.
Baron was the goalkeeper for South Africa at the 2000 Olympic Games in Sydney and won 30 caps at under-23 level.
He was picked as the first choice for Bafana Bafana at the 2004 Africa Cup of Nations finals, but was dropped after conceding four against Nigeria.He started his career at Hellenic before moving to Norway. When he came back to the PSL, Baron joined Kaizer Chiefs in January 2005, before moving to SuperSport United in mid-2009.
