The 30 year-old former world title challenger was shot in a kebab shop in the city of Essen two days ago by an unknown perpetrator and immediately underwent surgery in Germany.
Charr is now recovering in hospital despite initial fears for his life and career, although no official word has been released from his manager regarding his future in the sport.
The Lebanon-born fighter has won 28 of his 32 professional contests since entering the paid ranks in 2005 and was highly-touted as a potential future world champion until a recent slump in form.
‘Diamond Boy’ went 21-0 to gain a 2012 challenge against former the now retired WBC title holder Vitali Klitschko in Moscow, Russia but was halted in four rounds and has never been able to regain a foothold at the top of the rankings.
Three defeats from his last five bouts put Charr in danger of become an also-ran in the top division, culminating in Mairis Breidis completely wiping him out via a fifth round pile-driver punch just two weeks ago in Grozny.
Since the incident, Charr has been inundated with support from the boxing community.
