Sturridge, who has endured an injury-plagued campaign, has missed the last three games with a hip problem and will again be absent for tonight’s Barclays Premier League trip to Hull (7.45pm).
Rodgers said: “It has been difficult for Daniel. Daniel is a good lad who obviously wants to play and be working and helping the team.
“But it has just been one of those seasons where he has been very unfortunate and he has missed out. We are going to have to monitor that day by day and see where he is at.
“When he has been fit he has been brilliant for the team. It is just the key now to see if we can get him back fit and consistently playing. We will see if that is going to be this season or the pre-season.”
Sturridge, 25, spent five months on the sidelines earlier this season with thigh and calf injuries.
The former Chelsea forward scored 24 times for the Reds last term and his absences has been keenly felt, compounding the loss of the prolific Luis Suarez to Barcelona.
The alternative strikers Mario Balotelli, Rickie Lambert and Fabio Borini have all failed to impress and strengthening the attack is likely to be a transfer market priority this summer.
Rodgers said: “We have already got a top-class striker in young Daniel, who is an outstanding player if we have him fit. But he also needs help as well.
“If you look at the numbers in terms of where we are at, after 33 (Premier League) games we have 47 goals. At the same point last year, after 33, we had 90. You are nearly talking about a 100 per cent deficit in terms of goals.
“So that is something that is clear. Defensively we have been strong, despite what people want to write or say. Those areas have been addressed but obviously the critical area, which was the case when I came here, is about goalscoring. That is something we need to improve.”
Liverpool, fifth in the table, were held to a frustrating goalless draw at West Brom on Saturday but Manchester United’s loss to Everton has kept their Champions League hopes alive.
Victory at the KC Stadium would take the Reds back within four points of fourth-placed United with both sides then having four more games to play.
Rodgers said: “It will be a tough game away at Hull, they had a good result at the weekend. But for us the idea is to go in and see if we can get the victory and keep putting as much pressure as we possibly can on the teams above.
“We can only focus on ourselves but we saw last year lots of changes can take place in the last five games or so. We just have to be prepared to give everything to finish as high as we can.”
Meanwhile Hull boss Steve Bruce has been boosted with the news that Mohamed Diame and Andy Robertson pushing to return from injuries which kept them out of the win at Selhurst Park, although former Cork City man David Meyler remains suspended.
And with striker Dame N’Doye continuing his recent hot streak with both second-half efforts against Palace, Bruce hopes there is still more to come from his £3m man. “Dame has got five goals in eight games which is a terrific return by him at just the right time,” added Bruce. “He usually scores his goals in bunches so let’s hope there are a few more around the corner and he can get the goals that keep us in the division.”
