John Arne Riise
Defender Fulham Premier
Riise suffered what is believed to be a hamstring injury during Sunday's FA Cup match against Sheffield United, according to the Daily Telegraph.
Riise had to be subbed off just 10 minutes into the match due to the injury, hurting himself on a sliding challenge on Ryan Flynn. The severity of the injury won't be known until he undergoes a scan, but he should be considered an injury doubt for Tuesday's Premier League match against Swansea City.
