Injuries, Progression

This week, I'll discuss some soccer injuries and progressions of serious injuries. Some great players have been taken out of their careers due to one nasty foul on this pitch. One example is Aguero; he's been injured since last November, and still expected to miss next week's game against Brazil, though he might return soon.
Also out since late last year is the one Messi. He's been out since last October from a nasty slide that disrupted his knees, and is still out indefinitely, meaning it's unknown when he'll fully recover. So far, Barça's learning to play without him.
On to a more recent injury is Arsenal's Petr Čech. His calf was injured on the third of March, during a game against Swansea, where he rushed back to his penalty box after a last minute corner, plus he reported to Arsene Wenger about a groin injury before the game, but says he was still a hundred percent confident to play; he almost made it through the whole game. Ospina made is return to play in place of Čech, but the Czech International is planning his return quite soon.
Finally for this list is the Yaya Touré. During yesterday's game against Stoke he had a suspected injury to his quads, possibly due to insufficient warm-ups for the game. Though his injury, like Čech's, wasn't caused by a dirty tackle, it still affects Man City's potential in the UEFA Cup, whose match is next week against Real Madrid. With him doubtful to be playing, City will be lacking Touré's signature free kicks, strength, and box-to-box midfielding.
