MANCHESTER UNITED have suffered a huge injury blow as Luke Shaw hobbled off against Luton.

Just minutes before the half-time whistle was set to be blown, the England left-back picked up another problem that Erik ten Hag later confirmed was "not a knock".

Shaw trudged straight down the tunnel to receive treatment.

He was spotted limping out of Kenilworth Road after the game.

Shaw was replaced by Victor Lindelof, who filled in at full-back with Aaron Wan-Bissaka and Tyrell Malacia in the treatment room.

There were fitness concerns regarding Shaw coming into the game after he was subbed off in the previous clash versus Aston Villa as a "precaution".

Ten Hag said prior to kick-off against Luton: "We built him up again during the week.

"It was not certain on Thursday at the press conference that he could play but he’s fine, good improvement.

"When he’s fit he has to play because definitely he will contribute to our levels in the game.”

Shaw has already missed 20 matches through injury this season.

And fans are growing increasingly frustrated over his fitness record.

One said: "We might have to buy a Luke Shaw replacement with all these reoccurring injuries."

Another added: "Sell him. He’s too injury prone despite his quality."

A third reacted: "They shouldn’t have risk him. I hope he won’t be out for long."

Those still on the pitch for the second-half have the job of protecting Man Utd's lead after they went two goals ahead inside seven minutes via a Rasmus Hojlund double.

But Carlton Morris pulled one back as the Red Devils went into the break 2-1 up.

The score remained 2-1 to ensure a vital three points for Manchester United.
