The 33 year-old, who went 30-0 until halted by the rugged Argentinian in ten rounds in Las Vegas, features at the Horseshoe against the 14-loss journeyman knowing he has to look good to get back in the title mix.
“I am glad to get in the ring after the lost to Matthysse,” Olusegun told World Boxing News.
“I know Griffin doesn’t look like he poses any danger, but I have to respect every opponent because just one punch can change any fight – so I won’t be taking any chance.
“At the end of the day I am fighting against a boxer – not a ping pong player and boxing is a contact sport, so you have got to respect your opponent.”
Olusegun then went on to suggest that he would eventually turn his crosshairs to a revenge mission against Matthysse in a bid to overturn his only loss.
For now, the Nigerian-born fighter has stated that he would be interested in stepping in for the injured Kell Brook against Devon Alexander on May 18, although with the champion in talks with Lee Purdy – amongst others, Olusegun knows there may be little chance.
“At some point I hope to fight Matthysse again to avenge my only defeat, but if Alexander needs an opponent I would be ready for it.
“I don’t know anything about Lee Purdy fighting Alexander so I can’t comment on what I don’t know, but we will see what happens,” he added.
