Fiorentina plan to give an update on the condition of Rossi's knee in three to four weeks time, Football Italia reports.

Rossi is a fighter who has come back from so many injuries. Chances are he will do well once again after he is declared fit.

Rossi will be sidelined for four-to-five months after undergoing yet another surgery on his right knee, ESPN FC reports.

Rossi was fit for the beginning of last season but had surgery on his knee in January was deemed not healthy enough to play for Italy in the World Cup. He'll now be sidelined again and people will start to wonder how much longer he can keep doing this.

Rossi will undergo yet another knee surgery after he hurt his right knee during training last month, Sky Sports reports.

Rossi has already torn the ACL in his right knee twice and while the latest surgery is a basic arthroscopic procedure, given this history with knee problems, it could be a while before Rossi returns to the pitch.

Rossi has reportedly been feeling pain in his right knee, and he has been told to rest for at least seven days, Football Italia reports.

For most players, a little knee soreness wouldn't be too much of an issue, especially before the season even begins, but with Rossi's history of knee injuries, any pain in the area is treated with extreme caution. He will likely undergo a scan in the coming days to determine the extent of the injury, and he could be in danger of missing the Serie A opener against Roma on Aug. 30.

Rossi was left off the Italy 23-man squad for the World Cup, with Napoli forward Lorenzo Insigne getting selected ahead of the New Jersey-born striker, ESPN FC reports.

Rossi missed four months during the Serie A season after suffering another right knee injury, but he appeared to prove his fitness since returning in early May. Rossi failed to make the 2010 squad as well, and it will likely be very difficult for him to make the 2018 World Cup when he will be 31.

Rossi scored Sunday in Fiorentina's 2-2 draw with Torino, giving him 16 for the season.

One has to remember that Rossi missed much of the second half of the season and was leading the league in scoring before he got hurt.

Rossi was named to the Italy 30-man preliminary World Cup roster Tuesday, Sky Sports reports.

Rossi was enjoying an exceptional season for Fiorentina before suffering a knee injury in early January. He returned to play in the final three matches of the season, scoring a goal against Sassuolo on May 6 for the 15th goal of the campaign. Rossi has seen his career ravaged by knee injuries, but it would surely be a high-mark if he's able to make it to Brazil.
