Injury expert reveals how long Kolasinac ruled out after 'horrible' Arsenal development

Sead Kolasinac could be out for up to four weeks at Arsenal depending on the severity of his ankle injury.

So says injury expert Ben Dinnery, who runs the Premier Injuries site and has a background in medicine and data analysis.

Kolasinac did not make the squad for the 4-0 defeat to Liverpool on 20 November and will sit out this weekend’s clash with Newcastle United.

The left-back suffered what Arsenal’s media team described on 18 November as a “significant” ankle injury while away on international duty.

The 43-cap Bosnia and Herzegovina man will likely miss up to four weeks of action while he recuperates, predicts Dinnery.

“It doesn’t look great,” he told Football Insider correspondent Adam Williams.

“It was a horrible tackle, really nasty. The Finnish player was rightly sent off. From looking at the footage, we’re looking at a lateral ankle sprain.

“In terms of the specifics, that could impact his return-to-play time.

“If it is just the lateral ligament, he has a chance of returning to play sooner rather than later. These things always look worse in slow motion.

“This season we’ve seen lots of ankle sprains. If there’s no tendum or bone involvement, we could be looking at somewhere between two and four weeks.

“Arsenal will want him for that festive period with the games coming thick and fast.”

Kolasinac, who spent the second half of 2020-21 on loan at Schalke, has featured just four times in all competitions this season.

Nuno Tavares and Kieran Tierney are well ahead of him in the Emirates left-back pecking order.

In other news, pundit claims Arsenal are “millions of miles off it” and “erratic” Aaron Ramsdale is not helping.
