A minor niggle forced the Croatian off in the win over Bournemouth at the weekend, but he could be seen training with the rest of the squad as normal on Thursday.
The images would appear to suggest that the former Southampton man is in contention for the clash with West Brom this weekend and perhaps more importantly, the Champions League semi-final first leg against Roma next week.
Joining Lovren in training was fellow defender Joe Gomez, who made his comeback from injury earlier this week.
The 'Reds' are unbeaten in six games in all competitions and currently sit third in the Premier League.
