Report: Cristiano Ronaldo Out for Manchester United vs. Manchester City with Injury

Manchester United forward Cristiano Ronaldo is reportedly out of Sunday's match against Manchester City with an injury.

Laurie Whitwell of The Athletic reported that Ronaldo will sit out after not being listed in Ralf Rangnick's 21-man squad. There was the possibility Ronaldo could have been a late arrival, but those hopes were dashed early Sunday.

Edinson Cavani, who hasn't played since Feb. 8, is also set to sit out the Manchester derby, likely putting a heavy onus on Marcus Rashford to pick up the goalscoring slack. 

Ronaldo has been in the midst of a slump of late, scoring only one goal this calendar year.

United, meanwhile, are enduring a disappointing season overall, sitting 13-8-6 in the Premier League, good for fourth place. They are 19 points behind league-leading Manchester City through the first 27 games of the season.

Ronaldo returned to United in August after leaving the club for Real Madrid in 2009. The 37-year-old spent six years with the club during the formative stage of his career.

United will hope his health improves soon in what is a lost season for both parties.
