Oxford boss Des Buckingham felt the heavy schedule of three games in six days took its toll on his team as they were held 1-1 by Stevenage at the Kassam Stadium.

It means it is effectively no longer in Oxford’s hands to reach the League One play-offs because Lincoln are three points behind them with a game in hand and a superior goal difference.

Buckingham felt the decision not to award the U’s a penalty when Marcus Browne appeared to have been fouled by keeper Craig MacGillivray in the first half was crucial.

They had to come from behind as Stevenage went in front through a Sam Long own goal in the 32nd minute, Cameron Brannagan replying from the penalty spot on 58 minutes when Carl Piergianni fouled Ruben Rodrigues – though that appeared to have been outside the box.

Buckingham said: “To play three games in six days is a big ask.

“We had 26 shots but couldn’t get that second goal we needed.

“There was a clear penalty not given in the first half, and for us that’s the second game in a row that one hasn’t been given when it should have been. It was a huge moment in the game, and very frustrating.

“The referee told me he couldn’t see it, but the linesman was only 15 yards away and had a clear view.

“I’m delighted with the performance but ultimately we’ve got just the four points from these three home games, now we need to make sure we prepare right and get three in the last one at Exeter.

“When we looked to rearrange the Lincoln game we chose this week because it was a free week, then Sky told us they wanted to bring this Stevenage one forward and show it on the Friday night which meant three games in six days.

“There was nothing we could do about it, but had we known they were going to do that, we would have played the Lincoln game another week.

“It’s going to be a tight finish – I wouldn’t rule out Blackpool either, and they’ve got to play Barnsley.”

Stevenage had lost manager Steve Evans in the week, with Evans heading north to become Rotherham boss.

Caretaker boss Alex Revell said: “Steve always had two clubs very much in his heart – this one and Rotherham. Believe me, making the decision was probably the hardest thing he’s had to do, he said.

“I wanted to take today and make the players ready. I really enjoyed it because they gave everything.

“I’m very proud of what the lads did tonight.

“We had a great day yesterday in terms of training and getting ready and trying to get a few bits into them.

“They came to a really tough place and worked so hard for each other.

“In spells we created some half-chances, probably not enough, but it was about showing our togetherness as a club and our spirit.

“I think we showed why we have caused teams problems this season, especially with our energy and our workrate.

“The first penalty shout against us was a penalty and should have been given so we got away with that.

“But it doesn’t mean that something that started outside the box should be a penalty. Two wrongs don’t make a right.”

Oxford squandered a great opportunity to strengthen their bid to reach the play-offs when they could only manage a 1-1 draw at home to Stevenage.

It leaves them in sixth place in Sky Bet League One, three points ahead of Lincoln, who have a game in hand and superior goal difference.

Stevenage, who lost manager Steve Evans to Rotherham this week, held out for a point despite not having a shot on target – they scored through an own goal – and being under constant pressure.

Stevenage took the lead against the run of play in the 32nd minute when defender Sam Long, pressured by Kane Hemmings behind him, turned Nick Freeman’s left-wing cross into his own net.

The U’s felt they should have had a penalty when Ruben Rodrigues threaded a pass through to Marcus Browne, who looked to be fouled by goalkeeper Craig MacGillivray in a race to reach the ball.

But referee Tom Nield ignored Oxford’s appeals for a spot-kick.

They were awarded one in the 58th minute, though, when Carl Piergianni brought down Rodrigues on the edge of the box after the Portuguese forward got goalside of him. Cameron Brannagan converted.

The home side dominated the first half, with MacGillivray saving Rodrigues’s fierce drive, Long glancing a header just wide at a corner, and Mark Harris nodding wide from a good position.

The second half saw much of the same, MacGillivray saving from Finn Stevens and from Josh Murphy when he raced through.

Stevenage nearly won it late on as Long cleared off the line and then a shot was deflected off a defender and against a post.

Max Sanders’ first-half goal lifted Leyton Orient back into the League One promotion picture with a 1-0 win at Stevenage that saw the hosts drop out of the play-off positions.

Sanders scored the only goal of the game in the 16th minute when, after being found in the box, he shifted the ball onto his right foot before sliding a shot under Craig MacGillivray.

Stevenage striker Jamie Reid thought he had pulled his side level 24 minutes in but referee Craig Hicks disallowed his goal for an apparent handball against Jordan Roberts.

Boro’s top scorer threatened once more when he flicked Dan Butler’s free-kick into the hands of visiting goalkeeper Sol Brynn as Orient survived again.

Home boss Steve Evans made four substitutions at half-time in a bid to turn things around.

However, Stevenage could only muster three hopeful efforts in the second half, from Reid, Roberts and Nick Freeman, as they dropped to eighth in the table, just three points above Orient.
