Modric could be sidelined for up to five weeks after picking up a knock in Croatia's match against Italy on Saturday, Football Espana reports.

Modric will undergo an MRI to determine the severity of the injury, but the injury certainly isn't good news for Real Madrid, who could be without their midfielder until the holiday break.

Modric picked up a knock and had to be subbed off in the 79th minute in favor of Alvaro Medran.

Manager Carlo Ancelotti did not give any further details regarding the injury after the match, but Modric is considered an injury doubt for Wednesday's Champions League match against Liverpool at Anfield.

Modric picked up an assist and took one shot during Real Madrid's 5-0 rout of Athletic Club on Sunday.

Modric has scored a goal and assisted on another in his last two league games, a solid output for a player who tends to play a little more defensively. He's been able to creep up a little more this season thanks to Toni Kroos, although he's still unlikely to be a double-digit goal scorer like so many of his teammates. That being said, he could fall into double-digit assists passing to the likes of Cristiano Ronaldo, Gareth Bale, Karim Benzema, and James Rodriguez, among others.

Modric scored his first goal of the season in Real Madrid's 2-0 win over Villarreal on Saturday.

Modric is a vital piece for Real Madrid, but his fantasy value is a bit limited given his role. While he'll likely fall into a few assists with the incredible weapons around him, he's likely not headed for double-digit goals this season.

Modric set up Gareth Bale's 30th minute goal during Real Madrid's 5-1 Champions League victory over FC Basel on Tuesday.

Modric doesn't get involved in the attack as much, but he does now have two assists in his last three club appearances. With so many goal scorers on the pitch with him, he should certainly fall into a fair number of assists this season despite playing a more holding role.

Modric set up Gareth Bale's 11th minute goal during Real Madrid's 4-2 loss to Real Sociedad on Sunday.

Modric plays primarily as a holding midfielder, so he doesn't produce a ton a lot of goals, although he has been able to grab a few assists here and there, especially since he's surrounding by such incredible talent all over the pitch.

Modric has signed a new contract with Real Madrid that will keep him with the club until 2018.

Modric has fit in seamlessly at the Bernabeu, but he doesn't offer too much fantasy value now that he's not operating as far forward on the pitch. The 28-year-old Croatian midfielder has already made 67 league appearances in two seasons with Real Madrid.
