Thomas Partey was examined for a rib injury following Arsenal’s defeat to Manchester City

Thomas Partey is due for an MRI on Saturday to assess the extent of a rib injury he sustained in Arsenal’s defeat to Manchester City on Friday night.

The midfielder started the match at the Etihad but did not return in the second half and was replaced by Albert Sambi Lokonga as the Gunners lost 1-0 thanks to a goal from Nathan Ake.

It was not clear at the time what had happened to the Ghanaian, but it has since been confirmed that he felt pain in his ribs and Arsenal boss Mikel Arteta says he will be sent for a scan.

“He felt something and we didn’t want to take any chances, so he couldn’t continue,” said Arteta.

“He experienced some discomfort and it got worse, so he couldn’t continue. He didn’t feel comfortable going any further.

“Of course he’s going to have an MRI tomorrow, the day after tomorrow, and see what he’s got.”

Partey has been in fine form for the Gunners so far this season and his injury will be a major concern for Arteta as they continue their challenge for the Premier League title.

However, a replacement could be on the way soon after a £60 million bid was made for Brighton’s Moises Caicedo.

The Seagulls want more than £80 million for the Ecuadorian, but he has confirmed he wants to leave the club, so a deal could be in sight before the transfer window closes next week.
