Mario Gotze will be out for Borussia Dortmund indefinitely.

Those investigations revealed the player has metabolic disturbances, rendering it absolutely necessary to withdraw him from team training for the time being.

"I'm currently undergoing treatment and will do everything in my power to be back in training and helping my team to achieve our common goals as soon as possible," Götze said.

"We're happy to have now uncovered the reasons for Mario's difficulties and are convinced that his extraordinary abilities will give us additional quality once he has completely recovered from this," emphasised Borussia Dortmund's Sporting Director Michael Zorc, who continued: "Mario has the full backing and maximum support of everyone at BVB during his recovery!"

Clint Dempsey has been cleared to train again with the Seattle Sounders several months after being diagnosed with an irregular heartbeat.

Dempsey spoke to the media for the first time since he was diagnosed with the irregular heartbeat in August and his season was cut short.

“It was a heart issue. It’s something that’s difficult to kind of explain,” Dempsey said. “But at the same time I’m not feeling those things any more and I’m happy to be back playing.”

Dempsey estimated he’s probably at 85% to 90% of his full fitness level right now after starting a closely monitored exercise regime before training camp.

“I was able to consistently progress and work on my fitness and make sure everything was moving in the right direction,” Dempsey said. “It started off slow and had to work my way up and still working up now but feeling like I’m finally getting close.”

Gabriel Jesus has suffered a fractured metatarsal and could be out for the rest of the season.

The normal time for recovery and recuperation from a metatarsal injury is between two and three months, so at best Jesus might be looking at a return in mid-April.

Jesus was withdrawn after 15 minutes of the game at Dean Court after he fell to the ground in obvious pain, and from the way he removed his boot and pointed at his foot a metatarsal fracture was suspected at an early stage. 

In just five games since joining City at Christmas, Jesus had not only scored three goals but succeeded in displacing Sergio Agüero from the team.
