The injury to Havertz, 26, leaves the Gunners with just one healthy center forward — new signing Viktor Gyokeres — as Gabriel Jesus has yet to return from last season's ACL injury.

We don’t know any details and so speculation about Havertz’s injury and what Arsenal will do is just that — speculation. Havertz could miss a couple weeks, a month, a couple months, or the rest of the season.

Arsenal are waiting to see if Kai Havertz is going to be on the sidelines for a period of time after the forward picked up a knee injury. The 26-year-old was not part of the open training session held at Emirates Stadium on Wednesday and the injury is being assessed by the medical department.

Kai Havertz came off the bench in Arsenal's opening day win over Manchester United, but is now set for a spell on the sidelines with the Gunners poised to return to the transfer market

Leeds United started life back in the Premier League with a 1-0 victory over Everton at Elland Road on Monday night, and they take on Arsenal next at Emirates Stadium on Saturday. Leeds will be facing one of their fiercest oppositions this season this weekend given how impressive the Gunners have been in the last three seasons.

Arsenal had an open training session at the Emirates on Wednesday before their first home fixture of the Premier League season when they host Leeds United on Saturday. Ben White and Kai Havertz were glaring omissions. White came off in the 71st minute in the win at Manchester United on Sunday and Havertz started the game on the bench.
