The pair were not included in the Liverpool squad for Saturday night’s Premier League clash at Selhurst Park, having been substituted during the second half against Real Madrid in midweek.
“They are both injured,” Klopp told Sky Sports before kick-off. “So, Darwin had the shoulder problem from the Newcastle game.
“[It] worked out for the Real Madrid game but then [he] got another knock there, felt it again and more so there was no chance for today. Hopefully he can be [back] in midweek again.”
