Winger Danny Green faces a spell on the sidelines after being stretchered off against Cambridge United this afternoon.
The recalled wideman went down on 20 minutes with what appeared an innocuous challenge, but had to leave the field with his leg in a brace.
Green has since tweeted: “Thanks for your messages! Think iv done my ankle ligaments! Hopefully be back soon! Good point, fans were class!”
When asked about the incident, boss Nathan Jones said: “Danny’s rolled his ankle, which is unfortunate for him as coming into the side today, I thought he started quite well.
“It’s a little bit frustrating, but is one of those things, we’ll assess it and see where we are on Monday.”
Green was one of three Luton players who had to go off injured, as Mark Tyler was forced off after just eight minutes for Elliot Justham.
In the second period, Ryan Hall had to be substituted too, while Jack Marriott was struggling for the final stages as well.
On Tyler’s injury, Jones added: “I’ll have to speak to the physios but his back seized up and very early we’ve lost two players.
“It’s things to try you and test you, it meant we couldn’t go quite as positive later in the game because we didn’t have the subs to do that as had to make two early ones.”
