Blues boss Antonio Conte confirmed that the Belgian will be surplus to requirements should the signing of Edin Dzeko go through.
Chelsea are still in talks with Roma over a double deal that will see the Bosnian striker and left wing-back Emerson Palmieri move to Stamford Bridge.
Batshuayi still holds out hope of making Belgium's World Cup squad, but needs regular first team football to be in contention.
Kenedy has been allowed to go to Newcastle for the rest of the campaign to get minutes under his belt.
"It's the same as Kenedy," Conte said. "If arrives another striker, then Batshuayi will go on loan.
"I think he wants to have the opportunity to play with regularity. I think this is right.

“We have to try to make the best decision every time for the team”
Antonio Conte
"If we stay with the same players from the start of the season, it doesn't change. One player goes out, one player comes in. One player comes in, one player goes out.
"I think we have to try in every moment to be honest with our players. I don't know if another striker will arrive for Chelsea.
"But, in this case, I don't want to send away any player.
"But a lot of times it's the player saying he prefers to go away to have the possibility to play regularly.
"Then you have to show you deserve to play every game.”
Conte dropped a major hint that Batshuayi won't be in the first XI to face Arsenal in the Carabao Cup tomorrow night.

He added: "I don't know if this is the right time. I think that every player had their chance to play and to show me their value.
"Now I think I have to make the best decision for the team. Every game is different.
"The quality of your opponent is different. I have to make the best decision to try and exploit my players in the best way.
"Our job is not simple, not easy. We have to try to make the best decision every time for the team.
"And to try to improve our players. Sometimes we are able, sometimes we are not able. But you have to do your best to reach your target.”
