Liverpool midfielder Naby Keita has collected a knee injury.

Keita was among four Reds players replaced shortly after the hour in Sunday's 1-0 FA Cup quarter-final win at Nottingham Forest.

The 27-year-old was due to meet up this week with the Guinea national team ahead of their friendlies against South Korea and Zambia, reports the Liverpool Echo.

The Guinea FA, though, confirmed on Monday that Keita has not travelled due to a knee issue, with the Reds now hopeful the midfielder doesn't face an extended spell on the sidelines ahead of a busy April schedule.

Keita has featured prominently since returning from the Africa Cup of Nations in late January, starting four of Liverpool's last six Premier League games and also coming on from the bench in both legs of the Champions League round of 16 tie against Inter Milan.
