Ljungberg jogged during training with teammates in Stockholm, according to the Swedish FA.
The midfielder was the only member of the Swedish team absent from two recent training sessions, as he underwent rehabilitation exercises on his injured right foot.
“My foot feels great,” Ljungberg said after training. “Unfortunately I’ve been in the gym, which I hate,” Ljungberg added.
Ljungberg will be available for Sweden’s World Cup warm-up match against Chile this Friday, Sweden’s coach Lars Lagerbäck said.
“If all goes to plan, he will play. The rest (period) has been perfect for him,” Lagerbäck added.
The 29-year-old revealed last week that his battle against injury includes having blood drained from his foot after every match.
Ljungberg has been plagued by a string of injuries to his hip, calf, shoulder, rib, hand and toe since Sweden’s second round defeat by Senegal at the 2002 World Cup.
