The former undisputed champion of the world was taking in fight week for Sergey Kovalev v Andre Ward when Lewis was asked his thoughts on Parker, who fights Andy Ruiz Jr. for the vacant WBO title on home soil in New Zealand next month.
“Parker’s okay, he’s just started and he’s got a lot to work on, a lot to do, and we are going to have to see how he fares,” said Lewis.
“It all starts with the jab. If he starts off with the jab he shouldn’t do too bad. If he styles after me, he’s got to have a good jab … long, lose and dangerous.”
On the same December 10 date, Anthony Joshua puts his IBF title on the line against Eric Molina, a fight which Lewis believes will be another one-sided affair for the 2012 Olympic champion.
“I think Anthony Joshua has a good fight in the sense it’s not going to be difficult. Obviously, he’s still got to watch out and not take any chances.
“I think it should be a three round fight for him,” added Lewis.
The winner of Parker v Ruiz is set to fight David Haye in 2017, whilst the Joshua v Molina victor is a possible to face Wladimir Klitschko for the WBA ‘super’ belt.
