Gerrard scored from the penalty spot after Daniel Sturridge was tripped by Danny Rose to put Liverpool 2-1 up and take his season goal tally to double figures, but he was forced off with 20 minute to go with a hamstring strain.
He looks set to miss this weekend’s FA Cup fifth round tie with Crystal Palace, and manager Brendan Rodgers will hope to have him back sooner rather than later with the Europa League last-32 double-header against Fiorentina getting underway next week.
Liverpool injury list
Liverpool injury list
1/5 Adam Lallana
Replaced against Manchester United after picking up a groin problem, missed the game against Arsenal and is unlikely to return against Blackburn.
2/5 Jordan Ibe
The promising youngster has been out with a knee injury but returned to light training last month.
3/5 Brad Jones
A thigh injury forced the goalkeeper off on Boxing Day last year with no return date set.
4/5 Jon Flanagan
Hurt during pre-season, the defender is still yet to feature this season. Training is becoming more intensive for the 22-year-old and he played a small cameo in the Steven Gerrard charity game at Anfield.
5/5 Mario Balotelli
Missed the game against Arsenal but could be fit against Blackburn after training with the first team.
Rodgers’ assistant manager Colin Pascoe revealed the injury after the game, and confirmed that the 34-year-old will undergo a scan this morning to determine the full extent of the damage.
"Unfortunately he felt his hamstring towards the end of the game and he is having a scan this morning and we are just waiting for results to come back,” Pascoe said.
Gerrard’s absence adds to Liverpool’s problems in midfield, with defensive midfielder Lucas already ruled out for up to six weeks having suffered a thigh injury in the weekend draw against Merseyside derby rivals Everton.
Raheem Sterling was another to pick up a knock in the game at Goodison Park, but the England youngster could return against Palace on Saturday if he passes a fitness test in his injured foot.
Pascoe added: "We are monitoring Raheem. He missed a game the other night but we will see how he is.
"Hopefully the scans (on Gerrard) won't show too much but as we've not got the results I can't say too much."
In the absence of Gerrard and Lucas, Rodgers has limited options in the middle, with Joe Allen and Jordan Henderson set to be joined by one other in a three-man formation. Rodgers could look to sacrifice one of those midfielders and play Mario Balotelli alongside Daniel Sturridge following his match-winning cameo on Tuesday, although Emre Can could also be moved forward from his current position in defence.
Can is a natural midfielder, although he has adapted well to the right-centre-back role he’s found himself in recently and he was rewarded for his form with a nomination for the Premier League Player of the Month.Reuse content
