Oxford came from behind to hold promotion-chasing Luton to a 1-1 draw in a blood-and-thunder clash at the Kassam Stadium.And they had enough good chances in the second half to have won it. The Hatters, backed by nearly 2,300 travelling fans, took the lead in the 36th minute when Jayden Stockley stuck out a foot to divert Shaun Whalley's low miss-hit shot past goalkeeper Ryan Clarke and into the bottom-right corner for his first Luton goal. Oxford were angry that play had not been stopped in the build-up to the goal when Danny Hylton appeared to have been fouled. But the U's equalised in the 43rd minute when Johnny Mullins drilled home a low shot from eight yards when Luton were unable to clear Michael Collins' right-wing cross. Oxford produced wave after wave of attacks in the second half. Debutant Alex MacDonald twice went close with drilled low shots, Patrick Hoban had a goal disallowed for offside, and Mullins headed wide from seven yards.
